I'am actually not able to deny the “ask for publication” permission when i check the “block right inheritance (bloquer l'heritage des droits) on a custom section.

I see the associated permission when I add it but i disappears once I saved it

Is it a bug ?

EDIT : seems the bug apply only on some group. I don't manage to get the criteria. Typically i have some doc_xx_lecture groups that always bug (only when right inheritance is disabled)
