How to NOT display "Comments are off"?

On my blog posts it is displaying this:

Comments Off
--------------------------------
Comments are closed.

The "Comments off" and horizontal line are in grey colour, the "Comments are closed" are in blck (if that helps anyone pinpoint which plugin or which code is making this show).

I dont want to display either of these messages, if comments are closed.

Where do I edit this?

I am using Studio Child theme, if that helps.

Thanks
