Glitch in Profile Walls?

I have profile walls active for my users.
I have replies enabled in the plugin.

The wall owner can reply to posts by other users on their wall.
Other users cannot reply to or comment on posts by the wall owner.

If an administrator visits a wall they can reply to posts on the wall, but the post is labeled as being made by the wall owner.

Is this how the wall is supposed to work?
 

It should allow anyone that is a member of the group to reply and/or post on the wall. Seams to be working as intended in my tests. This is also working fine on our demo site below.

demo.cbdemosites.com/

I cannot test that, the link takes me to a sign in box. as per attachment. 

All the members on my live site are in the same group: "registered"

I have now managed to login to the demo site. I had to hit cancel to the sign in box to be taken to the demo site.
I can see replies to comments is working on the demo site, but I am now at a loss of where the switch is to allow users to comment to a wall post.

That'll show up if you try using the demo site while it's resetting. It should be fine to try in a few minutes after seeing that.

Sorry, I misunderstood your post. I thought you were talking about the CB GroupJive Wall. Are you referring to CB Activity and the Activity tab or CB ProfileBook and the ProfileWall tab?
