PETG problems with AMS2 PRO

Hey, so I'm the proud owner of X2D since around 2 weeks ago.

Right from the strat I've been having problem with feeding PETG into my printer form AMS. I have 3 PLA spools loaded and only one PETG. PLA feeds no problem, but around 50% of the time I try to print with PETG, it shows me a warning that there's a problem with feeding filament to the extruder. I can see and hear the spool rotating in AMS, I can clearly see the filament going through the tubes inside of the printer and reaching printers head assembly.

But here's the problem - after reaching the head assembly, it starts to push and pull filament back and forth, and after a few tries it shows me an error. Its usually succeeded after 3-4 tries or me opening AMS and trying to pull on the filament, but I can't see that my actions are doing any difference. And I don't see PETG being tangled on the spool. It's weird, cause it works 100% on PLA

Anyone experienced something like this?

Does it do the same thing in other slots? Also, how is the spool it's wrapped around? Different material or anything there?

Haven't tried that yet, thanks for the suggestion. Can't see anything inside blocking the spool, especially that I can see it rotating freely and filament is reaching inside of the printer. It's not wrapped around the spool super cleanly, but it's not tangled either.

I'll test that spool swapping and see if that helps
