When I assign Banners to countries, they do not assign to the selected countries, but assign to all countries, is there a known Fix to this error please.

I have sent a ticket well over maybe 2 weeks ago, and also a follow up days ago asking how things are going. On both occasions I have had no response, I know to ask in support these questions, but if support does not have support, then I am left to ask here, as I need to fix this bug so I can move on.

Thank You
