User cannot edit their own reply. RESOLVED.

Update: I changed some CSS which resulted in making the icon invisible. As I passed the cursor over the area... it became 'visible' again.

Please learn from my mistake!  ***

How can I pull this off? Certainly we do not want a standard user to "edit any discussion". Only to edit their own. 

In the system, "Comments edit own" is checked. 

Also, I notice I cannot edit these replies even as a moderator or administrator although I have those permissions.

Thank you.
