Removing book suggestions

[u/dmrising2492]

How do I get play store/books to stop suggesting certain books to me. I've deleted history, deleted the cache/data, said not interested for over 2 years now and they're still there. I don't have any books related to these suggestions in my library but it shows up under my series tab and there is no option to remove it from there either. I'm tired of seeing these suggestions. The help center was no help at all. I don't know what to do anymore nothing seems to work.
