Actor Steven Kampmann is showing under the wrong name in all of his actor credits (and removing his image).

Bobby von Hayes is a pen name he uses occasionally as an author, but it has somehow overridden his correct name and image from TMDB in all of his credits.
There seems to be a similar glitch for actor Joe Penny. His image has randomly been replaced by an unknown, but the same image has been on TMDB forever.
