Hello,
All you presets should be in your main preset folder located at the path you have set for your resources in ASC. They should not be lying around everywhere, if it's Arturia application presets.
Have you checked, if you still have the presets in your preset folders?
I assume the presets are there. And if so, then you can try to delete the db.db3 file in your main preset folder. The database will then be rebuild, when you open an application. You can in example open Analog Lab, and then let it be open, while the datebase build.
I hope that's it.
