Hi,
New here with A1-AMS lite/Windows 11, printer calibrated and restarted.
AMS-lite has: 1-eSun PLA, 2-Bambu PETG HF, 3-Bambu PETG HF, 4-Bambu PETG HF.
Having issues with filaments when they are not showing correctly in Bambu Studio, please do not judge to hard if I am doing something wrong, still learning 
It is started several days ago, before it worked 50/50… Tested deleting profiles in… AppData\Roaming\BambuStudio\user\9167411585\filament, still fails…
When I am opening any/different print profiles in Bambu Lab from Maker World, in Prepare mode I see(pic. a1) only 1 filament(Bambu PLA Basic) in spooler 1 and nothing else. Read that I can click Synchronize or just manually add correct filaments. I did Synchronize and another pop up window(pic. a5) saying about to save preset(I am confused here) then I click OK and finally I can see(pic. a6) all my correct filaments.
So, when I slice the plate and then click Print plate in the pop up window I can see only 1st filament which is 1-eSun PLA and other 3 options are greyed out/unclickable. When I hover the mouse(pic. a7) above 3 greyed out/unclickable options I can see following message: “Note: the filament type(PETG) does not match with the filament type(PLA) in the slicing file. If you want to use this slot, you can install PETG instead of PLA and change slot information on the ‘Device’ page.”
So I can’t choose another filament from AMS lite…
Can some one please help to solve the problem with filaments?
What I am doing wrong? Thanks in advance!

I hope I understood the underlying question correctly, i.e. “why can’t I select the other spools for printing/how to be able to select the other three spools?”
With Material in slot 1 assigned to all parts in the assembly, that happens to be PLA. So the slice (gcode generation) is only usable for PLA. Hence the other 3 slots, loaded with PETG, can not be selected.
To select a different slot, either all other spools need to be of the same material (PLA), or all parts of the assembly need to be assigned a different material (PETG). Just select the “Assembly”, right click, “Change Filament” to one of the other slots and then slice (again).
Hope I understood the problem correctly,

Thank you for your replay.
I would like to have(on AMS lite) different filaments and be able to change between different filaments in Bambu Studio, so I think you understand me correctly 
Could you please guide me with your setup? I think I found the “Assembly” but can’t find where to right click, “Change Filament”…
It is a bit confusing with Bambu Studio for now…

Excellent 
On the left hand side, in the product tree, you have already selected the assembly. Right click exactly there.
A pop-panel will appear which contains a number of possible actions. “Filament” or “Change Filament” is one of these.
Just remember that you need to synch your project filaments first to have them easily available (i.e. getting to your a7 screenshot above). Otherwise, it can get a bit confusing.

I tried to find it…
Do not see it… 
Could you share some step by step screenshots if possible?
Tried to find it and finally discovered that I have to right click on the model it self and change the filament from pop up menu…
Thanks for your help!
But is it permanent solution? Feels weird to do all unnecessary steps just to change the filament…
