Hundreds of photos under wrong episode titles - how to fix?

Hi, I noticed a problem with the photos uploaded for some of the Fairy Tail anime OVAs. Specifically, entire sets of photos are under the wrong title names. There are more than 200 such photos, so manually reporting them or requesting deletions/uploads one by one would be impractical. The photos are not mixed together, just all in the wrong place. How can this be solved? I couldn't see any solutions on the editing pages. Specifics below:

https://m.imdb.com/title/tt7776460/ The title is "OVA 5: The First Morning", but the photos are all from https://m.imdb.com/title/tt7776466/ "OVA 6: Welcome to Ryuzetsu Land" (which has the wrong cover image as an aside).

Similarly, https://m.imdb.com/title/tt6923576/ "OVA 6: Fairy Tail x Rave Master" has all the photos which should be under https://m.imdb.com/title/tt7776476/ "OVA 8: Fairies' Penalty Game".

I suspect part of the issue stems from the titles themselves maybe having conflicting numbers with other references on imdb/elsewhere. For example, the above links have OVA numbers going from 1-10, including "The First Morning" at number 5. However, there is a separate numbering system here https://www.imdb.com/title/tt8324472/episodes/ where the numbers go from 1-9, with "The First Morning" not given a number but left as "Unknown" https://www.imdb.com/title/tt8324472/episodes/?season=Unknown . This would probably be why there are two different "OVA 6" titles above.

Thanks for any suggestions.
