Usual reply: whenever you see misplaced AI traffic or clearly wrong parking positions, it's never a problem of the scenery but, instead, it's always another AFCAD coming from another product in conflict. They usually come with AI traffic packages, but can also come with other sceneries for the same area that weren't unisntalled.
Use the free FSX Airport Scanner to find duplicates AFCADs for LSGG, and remove all the extra, leave on the one that comes with LSGG in the fsdreamteam\LSGG folder.
