HI, I got a contribution addition for Immaculate where I got no-votes based on the rule that production supervisors are not to be listed.
Fine with that.
The contributed roles however are supervising producers.

Now: the rules state that "Production Supervisors" are forbidden. However the role is "Supervising Producer" and the rules state "Do include "Supervising" credits in the above categories..."

Now as per https://en.wikipedia.org/wiki/Television_producer and https://en.wikipedia.org/wiki/Senior_producer, Supervising producer is an active producer role.
Production supervisor, as derived from the similar https://de.wikipedia.org/wiki/Postproduction_Supervisor, is a different role.

So: Different roles, it is not the forbidden production supervisor, so the rule to include "supervising" should be correct and the no-votes uncalled for, isn't it?

Indeed. "Supervising Producer" is a valid credit for DVD Profiler purposes, "Production Supervisor" is not.
