There are no duplicates as far as I can see (maybe I am looking in the wrong spot)?
You have another scenery in conflict, that's obvious from your screenshot, which shows objects that are not even part of FSDT LSGG. And misplaced AIs are another clear indication of this.
You can see all my sceneries, so far I have not downloaded any AFCAD files for any of them.
You might have not downloaded anything explicitly, but the conflicting sceneries are surely coming from a product you installed.
It's possible (yes, we saw all these cases) the FSX Airport scanner hasn't found any duplicates due to one of the following reason:
- The conflicting sceneries are not "AFCAD" types, but just .BGLs with objects
- The FSX Airport Scanner sometimes doesn't detect all duplicates, so you must find them and remove them manually. As I've said, the most common cause of such duplicates are AI traffic packages, but not only.
If you have GSX installed, it might help you identifying the offending one, by using the "Customize parking position", which will list the name of the AFCAD seen by GSX.
