Custom List Bug?

One of my custom lists has counted an extra entry (drama) for the title count. The title count at the top says 169 but when I go and check at the bottom of the list there is only up to 168. It's not super annoying but it bothers me a bit that it says 99% Watched because of it even though I've seen every title on my list. I don't have this problem on any of my other lists, only one. This list is currently private but if there is a way to fix this that doesn't require me to make a completely new list then I will of course make the list public temporarily.

 I'm thankful for any help or advice.

 Aoi:

Sometimes titles get deleted, so they will stay hidden for a while.

Why would a title get deleted? And what do you mean with "for a while"? Will it come back or...? I have no idea what was deleted so I'm just curious what you mean.

 samenai:

By deleted, it meant the title had been removed from the database. It can be for various reasons like being a duplicate or no longer allowed in mdl as per guidelines. When this happens, your custom list might not immediately update the numbers.

Ok I understand, thank you. It’s too bad tho that I don’t know what title is missing. Also it’s been like this for months now maybe even over half a year. I also assumed it would fix itself so I’m only asking now because it hasn’t.
