FSL A321 showing in Hub but it isn't installed

I don’t own the Flight Sim Labs A321 for MSFS but ever since it was released it shows up in the Hub as installed outside MSFS. It’s marked as available to update. I tried updating and removing it, but it soon reappears as ready to update.

I do have the FSL Airbus installed in P3D, but that is handled by the FMS Data Manager and is up to date. The Hub should only show things you have installed.
