Change collection title


When I let movies be grouped by collection, sometimes the language version used for the collection title is completely different from the one used for displaying the collection contents. So for example, the “Big Man” Collection would be titled in some Slavonic language (not sure which language it actually is), but the movies within the collection would be named in English.

Is there any way to change this behavior (or at least change the collection title, which seems to be impossible)?

Thanks in advance.

If I click the context button on a collection and go into Manage.. it lets me edit a collection’s title. In case you’re using this differently than I am, I’m in Movies > Sets.
