That sounded like a title, so I googled it and found that it might refer to the "universe" of some sort of Harry Potter fanfiction called "Resolving a Misunderstanding." If this isn't what you're talking about, then it's very hard to explain that phrase without knowing the context the author uses it in. Your guesses to the meaning would make sense if the phrase was "resolving a misunderstood universe," but as it stands the universe is the one doing the misunderstanding. Кароче либо это название какой-то коллекции фанфиков "Resolving a Misunderstanding" либо это что-то непонятно без знания того что автор имел в виду. Перевод наверно будет "Решение недоразумения"

Resolve an misunderstanding = remove a misunderstanding (by whatever means) The expression is used in the title as a play with words. I don't know the reason why. Maybe you can ask the author.
