Admin comments and user restrictions

Your question is actually pretty good, as you’ve found an edge case. The level (0-10) are still built into the roles system. So your custom role names collide with the built in capabilities. As role names get added as capability too, you should switch them to something more unique.

Hint: Roles are a flat system. So an administrator could have more capabilities than a custom role of toilet cleaner, but when they don’t share a single capabiltiy, then the one doesn’t have more “power” than the other one. So don’t try to see them as scale from 0-10.
