H1, h2, h3 etc??

Hi
First i have to apologize if my english is not the best.

ive just bought the Vantage theme and im wondering about the h1,h2 etc.
It seems that there is no way to choose where to put them, correct?
Im trying to put text etc in a headline widget and text</h2/ in a text and circleicon widget but its seems that it wont stick.

Why is that, what am i doing wrong?
I found a thread about the sam thing and the solution was to switch to editor and put the tags there put it does not work either

Thankful for all the help i can get because its a beautiful theme with alot of potential!
