Hello,
It's possible you have a corrupt database file.
You can try to remove the db.db3 file in your main preset folder that's on the location set for your resource folder in Arturia Software Center (ASC).
The file will be rebuild when you open applications. If you open Analog Lab, then let it be open some time while the database rebuild.
If this does'nt help, then you have to find out. if you actually have the presets twice somehow.
