Photos on Mac doesn't stop searching for location

I have scanned in a lot of old negatives which I am editing and since they have no EXIF-data with location, date etc., I am adding it manually, but for some reason, it got stuck for one of the photos, which I wanted to correct, since the location I chose was way off. (I won't get the exact coordinates, of course, but that doesn't matter much)

So is there a way I can get the process to stop? It's been going on for an hour now and that hasn't happened before and as long as it keeps searching, I can't change it.

I'll add a screenshot, but it is in Norwegian, but what it says is that it is searching for location info...

(Everything updated, by the way...)
