Missing shows from my watch history of an actor

I’ve noticed with a couple of actors that there is stuff missing when I click to see what I’ve seen them in.

A specific example for me is John Hannah

John Hannah · WeTrakr

Under TV Shows, it says I’ve seen him in these 5 shows

But when I check the Episodes, there is also Benidorm Is Murder and Celebrity Race Across The World

I also notice that on the Episodes page, nothing is showing watched on that page, but that doesn’t seem to be related to what’s showing up in the Shows page
