I recently upgraded to Pianoteq v9, and I'm encountering a frustrating issue on my macOS Mojave system.

Every time I reboot my Mac, Pianoteq loses all my imported user presets. I've tried moving them to the default location suggested by Pianoteq, but they still disappear upon the next restart.

Is there a known issue with user preset management in Pianoteq v9, specifically on macOS Mojave? Any suggestions would be greatly appreciated.
