Random tick symbols appearing on site.

Hi,

Any help with this would be much appreciated.

On a few pages of my site, I have noticed random tick symbols. They look formatted, maybe part of a setting? But I haven’t managed to find the source.

You can see them here on the forum page and on the social links at the bottom of this blog post

Please let me know if anyone has experienced this problem or knows any solutions.

Help would be much appreciated!

Thanks
