Centering a stubborn element with CSS

Hi there! This may seem small but it is driving me crazy. I'm using a plugin to use Yoast SEO's breadcrumbs on each page. I can't get them to be centered correctly though; they always get cut off on mobile... especially if the page title is long.

I don't want to modify the theme files to put breadcrumbs in in case there is an update.

This is one page you can see has issues: http://69.175.76.186/~johnhowardcompan/plastic-buckles-hardware/

Thanks!
