All printer settings gone when updating to Luban 4.13.0

All different printer settings are gone. When I try to import saved settings nothing happens. It just jumps to the normal setting without changing anything? What am I not understanding?

The material settings are fine.

What was your previous version?
Everything seemed to work fine for me updating from 4.12 to 4.13, but there are some older versions (3.x and maybe others if I remember correctly) that do not carry over saved settings because the update included too many new and rewritten features.

I’m not sure, but the gap was bigger that from 4.12. 4.10 maybe. How is the import function supposed to work? To me it seems like it does nothing but that may be me doing something wrong.
