Centered Logo moves right between 768 & 979px

Hi

I’m using the latest version of Customizr and WP

I have the logo centered but recently I seem to be having a problem with the logo moving to the right when the screen is between 768px and 979px break points, it’s fine and centered @ 980px and above also @ 767px and below.

It maybe due to some code I have in place before all of the updates happened but I can’t seem to find out why.

Thanks in advance.
