Non-existent town on map

That happens when people apply the wrong name to a road. Waze will try to draw a box to connect it to the other roads with that city name. So you can get a name spanning an entire country.

It doesn't impact finding addresses though.

And here is how it can be fixed.

I have noticed the same thing with the city polygon changing shape, appearing and disappearing, etc. I wonder if it is similar to very large landmarks -- those don't display their full shape unless there is a road with in each tile, which can be rare for large national forests. So maybe these ghost polygons are connected to tiles that either don't have any roads or just don't have roads which have been updated recently.
