Yes, now I was able to replicate this bug in the dropdown (pretend editing without saving). A bit tricky, because the darn thing wants to give me "Australien" because I'm on a Swedish IP number.
My guess is that WikiTree does not tap into the FamilySearch dynamically. The question is how often the location database is re-imported (or whatever the update is called).
Adding the tag SYSOPS may get the right attention.
