Hi dinos, there is indeed a bug there - the bug is that a cached older version of the objects can be used by the moi_commandprocessor.exe worker process and that means that recently applied changes to names and styles can end up being ignored. It's a little finicky to reproduce because the first time you try it there aren't any cached objects and so the current object goes through and it works ok. You've got to get a mismatch between properties on your current objects and cached objects in order for it to reproduce.

It's another manifestation of the styles bug that Brian reported here:

I've been working on a couple of different possible fixes for the next beta.

Thanks for reporting it!
