That question really should have been asked in the support thread for "Multi-Language EZ-Pages". I've never used that mod but, just by looking at the description, it looks like they DON'T share any of the same files, so it would almost have to be something to do with the way the information is sent to the menu.................something that the Multi-Language EZ-Pages has changed.

If you can't find out anything in that thread, let us know, and I'll try to look into it further for you, as soon as I can come up with some extra time.
