Group admins can't create member groups?

It seems like privileges are broken in this vital plugin 🙁
For example, we see that Group admins can’t create member groups as it is now with current WP /BP.

Anyone with a code tweak while we hope for this great and useful plugin to be updated for current versions?

Thanks!
