Actually, Bratyn has fixed this issue for Alsace-Lorraine in the 1.5.2 beta, so things should be better now at least (with Elsass-Lothringen being the territory held by France most sought after by Germany).
At least, but that's still a poor fix. I mean, you have to see the whole problem. If Axis beats the Allies, Germany will lose all occupied northern France in a peace conference. Nobody can have claims to Guangzhou port, African regions, Isles or South America territory. In case of a German win, it doesn't make sense, that Axis members can't claim these regions, because these areas are no part of Vichy France.
