Orcaslicer E-pa bugg?

Got a Problem… Whit Orcaslicer and setting up for a ke.

Orcaslicer. E-pa (nylon) is no generic version in filament list.
So i click filament, Add filament, custom filament, create new, set it up and its in my Filament list.

I could change settings and save… All fine till now.

Restart Orcaslicer, E-pa filament is gone… from my list?
Yes i can find it if i do the add filament again and then its standing under custom filament. But why it not stays i the first filament choice list?

If i do the same whit ASA and make a own version its present. Is this a Epa-CF bugg?
