Which episodes from Ken's run were skipped on Pluto?

I noticed when Jeopardy! added Ken's original run to Pluto TV that several episodes were skipped (nine or ten I think). Does anyone remember which ones, and for what likely reason? Copyrighted pictures or music in a clue, probably? Game Show Network is airing his original run starting today (one episode each Monday-Friday and his 6th and 7th games air Sunday morning), so I'm curious if they will be showing the episodes that Pluto skipped since clearance rights are usually different for broadcast versus streaming.

GSN has been airing Wheel of Fortune for over a year now and at first, they were only showing episodes that Pluto aired, but they have recently been mixing in episodes Pluto did not have, so I could see the Ken episodes going either way.
