Ok, I might have neglected that, .regionName is actually giving the Country Name, wasn't sure about that, for me it was a bit misleading.

Oh my, it was actually too late... I made a stupid mistake by not removing the Brackets [] ...

@Claude31 Thank you for your reply. Did you test it? I tried to access the objects the same way as you did but it doesn't work - actually the objects are arrays of objects and I access them through ¢Bindable vars - maybe the issue is here...
