Assets problems in UEFN

So in UEFN on my unpublished project i recieved a message that one of my assets violates the rules, i opened Creator Portal to see what preset it was and deleted it from my project but it still said that it violates rules, so i made an appeal where i stated that i deleted that asset fully from my project but it got decline, i need help cause i wont be able to publish my map at all. And i cant make another appeal. Also I have another question, is there a way for me to check my assets for rules violations before adding them to the project, maybe by contacting someone? Because i dont want to violate any rules and im not very familiar with them yet because its my first map, so they are kinda vague for me.

Uefn seems to keeps references, as they call it, of deleted things in memory, and the delete dialog says that the references can’t be deleted.
I found a way around it by migrating the cleaned up map into a brand new project, which is easy by just migrating the whole level, it takes everything that’s in it with it.
