Social Link block appears to be broken

I originally had a social link block in the footer of my site and it worked great. I wanted to make some updates to the site, so when I logged in I saw they weren't showing up anymore. The block is outlined, but no content. It doesn't appear in the + section anymore, but I can re-add it by typing it in and hitting enter. This does not fix the problem however. I also tried changing the colors and other details to make sure I didn't accidentally make it blend in with the background, but when I visited my site in a browser it doesn't even show the spacing where the block should be.

Is there any way to fix this?
