There are two different problems here.Problem 1.
Waze does not handle correctly two different cities (villages, settlements, etc.) having the same name. If two such cities exist, waze thinks that they are one big city and connects them. Now imagine three cities: a big triangle appears and may cover even whole map of your country, the ghost city name appears everywhere
. The best way to see the area of that ghost city is to turn off the Aerial layer in Cartouche.
The solution advised by waze HQ now is to include the name of the state/province/county/whatever into the city name so the names become different and waze software can distinguish and disconnect them. The problem disappears after the next map rebuild cycle.

This is the side effect of this problem: the false city name appears as the hint to all newly recorded segments. If you edit the segment (even its geometry!) and don't correct the city name it becomes permanent and remains in that place until you come back to the same place and edit it manually. This is how the false city may grow if you are not careful when editing. Fortunately, if you split the cities then the false city name is removed from the segments newly recorded before the split and still not edited. That's what makes me think that the city name of the newly recorded segment is a hint and appears as you start editing rather than a permanent property.Problem 2.
Even if you solve the problem 1. correctly and successfully, the ghost city name still appears at random places in the mobile client. This is really strange because in Cartouche the city areas are corrected. Even more strange is that the ghost areas are different at different zoom levels, some of them being correct. This makes me think that the tiles for Cartouche and for the mobile client use different databases or different rendering algorithms; Cartouche is correct and the mobile client (software or database) is buggy. Cartouche is a proof that the waze HQ has got a correct algorithm and a correct database. Why don't you use them for the client tiles?

Map editors color scheme is fine and we don't complain about it. My opinion is quite opposite: this color scheme is fine because it exposes the problem. It is not that other schemes are more correct. Ghost city name appear in all
color schemes in exactly the same way. The only difference in map editors' behavior is that it shows the area of the ghost city so you know not only its name
but also where
it is (incorrectly) placed. It is good for a reference and diagnostics. It helps to catch the ghost, other schemes just try to pretend that the ghost does not exist. But they don't hide the ghost successfully and it is still visible.

I have not noticed any way to undelete the city or street name. Is there really such feature in waze? Do you mean that the city or street name appears as the hint when you start typing? The hints are fine but I don't think that suggesting the name of a street or a city which has been deleted is necessary. Please note that the city/street name could have been deleted or edited because the old one has been mistyped. For me suggesting the mistyped name is even bad. If you don't like removing the name of the street or a city immediately and permanently then maybe these names should be deleted during the next map rebuild cycle or after a month of being unused.
But I don't think this is only a problem of the deleted cities because sometimes the cities which appear in the client really exist but in different place. For me it looks like some tiles have not been refreshed and still expose the city which used to cover this place. Sometimes I see the ghost squares in the places where no road segment exists. Sometimes I can also see them inside other cities while I am sure that the segments are corrected because everything is correct in Cartouche. And also it is not a problem that the map has not been rebuilt after the recent edit because in the place which I have reported to the waze HQ the ghost city was still visible 9 months after being removed.
note that our aim is to make waze better. The correct solution is to fix a bug, not to keep saying it does not exist. Map editors color scheme is not buggy because all schemes show the same problem, the map editors just shows it better than others.
