"Custom settings" (that aren't custom) blocking upload

I see other posts about this sort of issue, which seemed mostly to be intermittent MakerWorld server errors, but since these were my 1st 2 uploads I’m thinking it’s more likely that I’m misunderstanding something. I tried to post two models, w/ print profiles, and they both got:

Not allowed to upload a 3mf file that contains custom printer/process types or filament types

]

When I review the config in BS it looks pretty damn standard, and the profile comparer seems to think so too. [see pic

]

But I’m not sure what the difference is between saving the project and exporting a 3mf relative to saving a print profile (tried both though).

Also not sure what “custom” is supposed to mean here. I’d think the point of saving a print profile is that you’ve adjusted setting in some way. (In these cases, for example, I’ve enabled supports.)

I think I’m missing some basics on how this is supposed to work…

Did you change the Gcode?

Nope, not with either model. Thanks

The hoops keep multiplying, and we just keep jumping.
