H2 font is getting bold and appearing different than in the Upfront Editor

At this page (http://nobre.esites.pro/equipe/) “PROF. AMADEUS JOHNSON” title is an H2 tag. It appears normal on the Upfront Editor and bold when it is closed. Why that? Will I need to fix that on the CSS? Are you guys planning to let we choose the font weight as an Upfront setting as well in the next versions? Thank you!
