Font scaling issues in 7.1

Across browsers, 7.1 is suddenly not rendering the font styles that were set in the design settings. Anyone else having this issue? All heading styles are appearing enormous (even though the setting says otherwise) and standard paragraph styles are smaller, etc.. When I  attempt to edit in the font pack, they appear normal until after I hit save, then they revert back to being wrong. What's going on?

I’m experiencing the same thing. The best thing to do is contact support and tell them about the issue and they will pass it onto the development team to fix.
