Track presets custom tags disappear!

I try to build my Instrument Track presets library with some custom tags that I create but from time to time I can’t find my track presets with the tags …so I go see them in media bay and realize that their tags has disappear… I have to retag them …this is quite annoying !!

I’m on Cubase 13, Mac OS 14.1.1, MBP M1 Pro
