Deleting all expression events in midi items?

Tried doing this using the remove note expression command but they are still there (the main volume,etc.etc.)

I have found some midis play really weird with Cubase 13 compared to Cubase 12.

Voulez vous supprimer note expression
ou le midi cc11 ?
if it is note expression

if you want to remove cc11
There are already threads about this
Example:

Key command for this

What is certain is that you must use the midi logic editor
