Social sharing icons not showing correctly

Hi!

I connected my website to Jetpack and added the share this social media feature to my products and posts. The icons work great and is showing no problems on my product page and individual blog post pages, but on my main blog page, the icons are showing as little squares. I contacted support and they said it may be caused by a css code with ‘!important’ settings, but I can’t seem to find the problem. Is there a way to fix this? My blog page is: https://www.canekitchen.com/blog-posts/

Thank you for any help!
