Hi, same Bug here (since new BambuLab Update!) - after some fiddling-around, I got a DIY solution (hope it gets fixed very soon!):
Go to the 3. Tab (Device Settings) and at the right, you see a picture of the printer with the ETX spool. Double click in the windows with filament sort and the K-value. I wanted (and loaded) PLA and there was always PETG - so I changed by hand to PLA there and then the print was done right.
