Social icons visible when editing but not visible on published version

Hi everyone!

Hope you're doing well. Just having a weird issue popup recently where I can see the social icons when editing the site but become invisible on the published version. Any idea what might be causing it and how we can fix it?

I've tried a few things on the forum like removing and adding again but no joy. It's in the footer and header.

Many thanks!
