Submission Fails for 'custom' printer or filament

“Uploading a 3mf file that contains custom printer types or filament types is not allowed”

I get the error message quoted in the subject line when trying to post a model, but it’s a normal P1S with an AMS attached, and I’m printing with Bambu PLA Basic. What am I missing?

YES. I’ve experienced this exact problem many times.. I still don’t know how to solve this issue and it’s the only thing keeping me from uploading different print profiles to other people’s models. If someone has an answer.. please please please. I remember it working one time when I got a fresh 3mf as my base profile. I was accidentally using one from a previous project, and I had some custom filaments in the filament list that was messing with it.

I found the answer shortly after posting the question. I have, in my AMS, one roll of third party PETG I use for PLA support. Once I deleted all the extra AMS filaments in Bambu Studio, the submission went through. When I turn on the printer, it’ll rescan, or I’ll make it rescan the AMS, and everything will be back to my normal.
