extra padding on one element only for mobile

Hello, these 2 images are taken as screenshot from iphone. You cannot see issue on a mobile simulator tool, only when viewing on actual device. The 1st image is with NO Seraphinite activated. The 2nd image is with YES Seraphinite activated. You can see it is no longer centered. I would like to use this plugin as it does make my sight very fast, however, I cannot have this issue of product not being centered. It is the only issue that I can see. Is there anyway to resolve this?
