I want to remove the custom permissions from each of these users, so click on their username and select 'Quick Check All' on Inherit at the top, then Update Permissions.
Back to the Node Permissions, and the users still appear at the bottom suggesting they have custom permissions.
I then set an 'Allow' node permission for one of the users, saved, then set it back to inherit, and saved. No, still appearing. Then at /admin.php?tools/rebuild I ran 'Clean Up Permissions'. Back at the node permissions, and the users still appear as though they have custom permissions.
Not sure what I'm doing wrong?
