Are you using bambu lab filaments or generic ?
i noticed that if a generic filament isnt manually added in the printer itself, it doesnt show in the ams , you just get a slot with a little red circle inside, this slot can be picked and you will get unknown filament error ( it still prints )
after editing the printer
Are you using the synch tab to map ? rather than overwrite ( personally i think this is another unnecersary tab) and its better to manually edit colour ant type with the drop down boxes provided and in the printer as previously stated (generics)
For the best advice from the forum can you provide images as this will help others to help you.
