New(er) feature I believe, but when I tried to open a sequence where nothing had changed since I last ran it last winter, after converting the sequence for new version dialog, getting "the sequence has effects that belong to elements not known to this profile. would you like to map them to existing elements?" Well that description is pretty straightforward, except literally nothing has changed with the elements or sequence. Don't know if possibly that was a result of the conversion? That was more of a head scratcher than a problem. The issue is that if I say yes to map them to existing elements, the screen that opens just says Unknown name in one column. No idea whatsoever which element it's talking about, what it looks like etc
