[HELP] Can not set default boot priority

[Milkomenda]

Describe the bug
I already check the value of AllowSetDefault, that is true. But i cant use the key crtl + number/enter to do this, the option which is default seems like random. By the way, the EFI partition dont hide.
This error exists in both EFI, Either the original EFI (download from here) and the lasted EFI (Modified under the guidance of Dortania Guides ) .

Here is my EFI:

Sorry I don't have any suggestion for solving your issue modifying the EFI (you mean config.plist ? ).
Just to clarify, have you tried using the Startup Disk control panel to set the OpenCore startup volume? That should work. Or this does not address your issue?
