Store district should be a fixed city linked to its address.
For some reason stores can be associated to districts as well, which triggers a notification for all BOTs in that district, among other issues...
Steps to reproduce
Associate a store e.g. to "Deutschland"
What is the current bug behavior?
Association possible at all, all BOTs of that district get notified.
What is the expected correct behavior?
Association should only be possible to the respective city (or maybe region, but is there a valid reason?)
