If Wapedia is correct and all of these credits have Supervisor in the job title then I guess all of these credits should be removed??

If Wapedia is correct then "Yes".
It really comes as no surprise that there are several incorrect entries in the database.

But remember that the only authorative source for credits are the credits themselves. So before starting a bigger removal action we should take a look at them. It is possible that Wapedia is wrong.
