Print Customisation Issue

Hello, I’ve the feeling that custo isnt taken in account

I’m printing PLA and PETG
On PETG, I get lots of clogged hotend , and on PLA blobs and zits

I try to tune the print setting in the custom menu , but seemingly no change is taken in account beside saving

(i try to change the retraction , and the external extrusion %, but no visible change)

custom

For PLA, the cutom setting name is not event displayed.

Bonus:
Is the 3 custo options shared for all material or it’s 3 custo for each material?
