There have been other threads about this issue on some of the other boards. As I recall, there was no way to resolve, if you do not have a sub that covers that part of the world.
If you have a contact you trust ABSOLUTELY, who has a worldwide subscription, you could invite them, short-term, to your tree, with editor access. They could then view and "ignore" the hints.
Another option would be to upgrade to a worldwide subscription for 1 month, at the end of your current subscription, and "ignore" the hints.
I agree that it should not be, but those are the only ways around it, to my knowledge.
