Every menu that GroupJive creates cannot be edited. As menu type is blank, and there is no type for GroupJive, you cannot make any changes. Why is this?
Because the plugin has not been upgraded to CB 2.x and can't generate proper Joomla menu items. This is fixed already in the rewrite I am currently working on.
When editing a user's profile (for example to change access)can't be saved if you do not know that user's password.
The password fields should be empty and should allow save fine. If they're not then your browser autocomplete is filling them out. Clear your browser autocomplete/autofill to fix the issue. We've already set autocomplete="off" attribute for password fields so your browser or browser extension would have to be ignoring the attribute.
