As Jim has said, if the Language Setting feature of WBE is not enabled, it won't cause this.
Just to clear one thing up though, the Locations Helper is not only for American things. It does a variety of things, but one thing is that it gets the locations of the new person's family members and if it finds a match in the location suggestions, it will promote it to the top of the list and highlight it in green. If there are locations on the list which don't match the date that you have in the form, it will relegate those to the bottom and highlight them in pink/red (e.g. if one of the options is "..., United Kingdom" but your date is pre-1801, that location will be relegated to the bottom of the list).
The 'Correct Location' option is correcting a variety of locations that are given on the list (these are mostly things that people have asked me to correct) and adding some, too.
I don't know what could be changing your language option to Ukrainian.
