Marvel Anime Page

I found a page on IMDb titled "Marvel Anime". It consists of episodes from 4 different anime series already listed on IMDb.

The existing titles are: Iron Man, Wolverine, X-Men, and Blade.

Clearly, this is a duplicate page compiling all four series into one. I don't know the correct way to proceed. Should I request its removal? Or try merging each episode with those from the correct pages?
