Mailto social media icon in footer incorrectly formatting

I am using your excellent template in a new blog https://alistaircoombs.com/

I note that the inclusion of the phrase “mailto” in the social media menu brings up the icon correctly, however when I add the colon, for example when giving a full functional email link in the form of mailto:[email protected]—the formatting is altered and the button is blank and out of alignment.

I have simply left the word “mailto” there for now so the client can see the design, but I cannot figure out how to rectify this issue. Is it a known issue? Is there a fix?

Thank you!
