Thanks for posting in! This could be a bug in the parsing of font names in the theme. I've submitted this to our issue tracker so the developers will be made aware of it. Once they'll have it fix, it will be updated and rolled out in the next update release.
Meanwhile, please deactivate the X Typekit plugin and use the Font Manager instead. Please go to X > Launch > Templates > Fonts and set up the typekit.
To know more about Font Manager, please check this out:
Please bear with us.
