Catering provider/manager (Misc Crew) credited in IMDB as actor playing "Catering Manager" - surely a mistake

Rod Aspinall nm4764846 has Misc Crew credits as "Catering Provider" or "Catering Manager" for various UK TV programmes. But I notice that he is also listed as an actor playing "Catering Manager" for some programmes. For example, none of the episodes of The Knock tt0155436 that I have checked so far have him listed in the credits. At first I thought that somewhere in among the episodes there was a real on-screen actor credit, and that someone had mistakenly bulk-added this credit to many episodes. But I'm beginning to think that all the actor credits are spurious.

What do other people think? Should I move each of his Actor credits to Misc Crew (assuming it doesn't already exist) for each episode of the affected titles?
