Mobile Menu Padding

Greetings!

I have a question about centering some mobile page content which seems to have gone haywire on me. And as this is for my company's website, it is quite a dilemma indeed.

Basically, after adding some new buttons to our staff page, all the mobile content for that page has shifted off-screen slightly to the left, cutting off the text and part of the images, and leaving white space on the right. I am looking to center the content but haven't yet found an adequate solution.

The page can be accessed at the following (and again, this is a problem that occurs on the mobile only). All desktop functioning is still up to par.
