CMS images don't show up on Firefox or Safari (mobile)

I’m trying to create a simple marquee to display our team’s sponsors but some of the images don’t show on certain browsers.

These are the only three logos that appear on firefox and on my iphone.

[Here is my public share link: LINK]
(how to access public share link)

This is an example logo that isn’t rendering on firefox or safari.


It seems that it may be an issue with the SVG’s themselves as the ones that don’t render on the site also don’t preview using inspect element.
