I think I caused the error, because if I leave ui without any changes it works, but when I change ux code and zip it again and upload as Town.zip I cannot see it in navigation anymore no option City name under settings/map appearance menu.

I do not understand what the problem is, HEX code is just color....or maybe it breaks during unzip/zip process...

Simply if I touch anything i there it does not work, if I leave it like that (original) it works????
