Exactly.

Yes - I understand this is a pain. I've deleted

Yes, you have got in a mess here!

It does happen occasionally - if there's a specific action that can cause it, I don't know what it is, so you probably haven't done anything wrong.

We refer to these as sync errors. I've tried deleting the extra segments myself without success. If you're lucky it will clear by tomorrow. But more likely you'll have to wait for the next tile rebuild. Try
