Catfish UK is not showing up in Up Next. I checked the show options and Show in Up Next is on. Turned it off then on again and it still isn't showing there. I noticed it last week and same thing again this week.

Looks like you have one episode, S01E04
But the last episode you watched was S01E06. So the system is trying to only show you newer episodes than that.
Can you explain more about how you record and watch this show? Did you watch E6 before and then delete it, and E4 recorded after that?
That would explain it then. Not sure if its Gracenote or MTV, but they very first episode was Ep1, so they're showing them out of order it seems.
