Excellent, your screenshots convo what I have been saying all along.
You change all the colours of the swatches and now that they are all different p, you can see your model is assigned to the red-looking one.
This material is PLA, you have to,d the slicer it needs P,A, but, you want PETG.
Select the model, press the number 2 key on the keyboard or right-click the model and use the change filament option to change to the 2nd entry the cyan PETG.
The print dialog I’ll never let you choose PETG for a part you told it needs to be PLA. They are incompatible filaments with different setting requirements that the slicer knows are incompatible.
Once you tell the model which filament you wish to use by correctly assigning it, the print dialog will stop showing PLA in the top portion of the swatch and instead say PETG, it will auto detect any matching PETG and you can manually change it to any PETG in from those available in the AMS slots.
This is what I said yesterday.
