First SVG icon on mobile

Hey there,

I have a page with three svg icons that look great on Desktop but when I load it on mobile, the first one shows up blank (or transparent, since the link still is active).

I’m afraid that I’m not understanding what’s going on. I have tried creating a new CSS class just in case there are some inherited properties. However, I can’t replicate this on a desktop, even in mobile view. It also shows up blank on my phone.

The URL to the page in question is: Podcast
and here is the read only link: Webflow - The Resonance
