-1 casting suggestions shown in searches

There's a problem with casting suggestions. Some remain "-1 casting suggestions".

Something must be done about it as there are errors!

I searched for "Another World" animes and -1 were a result. No matter how many casting suggestions I make they just go up to 0.

I have also seen some of these negative number casting suggestions, and even though it feels like it will lead to nowhere, I am hoping this gets fixed as it seems like it has been an issue since at least 2022.
