Hello datysdal- I wish I had a solid answer for you; but (for me) it's difficult to tell exactly what might be plaguing your set-up.
The same type of issue has happened to me in the past and I've found that the group will appear if I navigate to another part of the WP admin area and then return to the FAQ system (after having received the successful "Your group has been created" message, of course).
I know that this isn't much help, but it may work for you.
If not, it could be that one of the edits made to the plug-in included an erroneous character (or some other typo) that is causing an error when attempting to process the creation of the new group.
If you're still experiencing the problem, take a look at the URL displayed in the same window that has the "Your group has been completed message." and see if anything looks strange with it.
You can, of course, paste a copy of that URL as a response in this thread & I'll take a look next time I'm around (you might wish to edit out your specific domain, using something like http://www.domainname.com instead, if you want to maintain a level of privacy).
Good luck!
