Since a few weeks I guess there are some visibility options missing. I cant find the options "show solo", "show party" and "show raid" under General Tab no longer. Usually I've turned my WoW Client to german language but I switched to english just to check if it is a locale issue.

I would like to create a new layout for solo playin including cell unit frames. But I'm not able to hide group frames due to the missing options.
I would be happy to hear thats not an issue and I'm just to blind to see the way to hide these...

After viewing the code changes in repo I found out that this must have to do with saved variables. So I backuped and deleted the Cell SV under ...%ACCOUNT%\savedVariables and now the options appear in the dropdown menus under Layouts as they should do.
Cant tell where exactly the prob is located but its fix for me.
