Additional system information

Printer

Bambu Lab A1 mini 0.4 nozzle(Upravena spona nahoru bbb.3mf)

How to reproduce

Load an existing .3mf project with per project printer settings. Loads OK.

Actual results

I clicked on 'Printer Settings' and then deleted the per project printer as I do not own that printer.
I then selected my printer which is a user preset printer and exited the dialogue.

I then discovered all my user preset filaments had also been deleted. None of my filaments have dependencies set.

Expected results

Only the per project printer should have been deleted.

Project file & Debug log uploads

Upravena+spona+nahoru+aaa.zip

Project file

Anything else?

Fortunately I had a backup of all my preset and was able to restore.
