no Filaments but "default" displayed to chose from after settings update
I'm using Prusaslicer 2.9.1 via Flatpak on Fedora.
Everything went fine until just now I got a new Filament (Extrudr Basic), clicked on add/remove filaments in the filament selection dropdown, selected an addition extrudr pla nx1.
In between i got a notice about some configuration update which i somehow confirmed (i really dont understand all these implication that are announced there about copying this and transferring that, i just chose the default choice there).
After that when returning to the normal operation screen of slicer, the Filament dropdown just says "default" and no other filaments are selectable.
Selecting "add/remove filaments" again i still see that there are multiple filaments schecked, but when ending the dialogue with "finish" the selection in the dropdown is still empty with nothing but one entry "default".
What can i do?
