Renaming Levels in Page Level Restriction drop down

Is there a way to rename the labels in the Page Level Restriction drop down.
Currently it says "Require Level #0 (or higher)"
My client gets confused by this and would like level#0 renamed to "Staff" and level#1 to Execs for example.
I have the S2Member General Options > Membership Levels/Labels > Force WordPress® to use your Labels? option set to YES. And I have renamed my first two levels.
However this doesn't seem to take affect.
Is this a bug?
