Help with hardened steel hot end with PETG and PETG GF

I am pasting screen captures to show you the warning I get. Though, it makes no sense in the fact that I selected properly the hotend type in the printer settings.

In this picture, it says in french: hardened steel 0,4 mm.

As you can see, the printer parts in bambu studio is greyed out and says hardened steel.

Now, when I try and print, I get the following:

And finally, I see the final warning.


The first warning says no AMS Lite, I know. Too brittle and could break.
The second says, that this is not the correct nozzle type. Now this, is an issue I think.

That’s why I want to try and find a particular build and revert back to it. Any thoughs?

Tks.
