H4 not displaying properly

hello! i changed the H2 font in highend options to a different one, and then changed it back to the default AbeeZee font. however, after i changed it back, other H sizes started displaying incorrectly. here is what was affected:

the special H4 font on my portfolio page (title for the “portfolio full width” module) got smaller: http://new.bethfuller.com/portfolio/food-network-ios-apps/

the titles for the “icon feature” modules on my “about” page got smaller: http://new.bethfuller.com/about/. see screenshot.

how to fix?

thanks!
