[Theme: Zerif Lite] About Us section formatting

Hi, I have a question regarding the Zerif Lite theme I am running.

Zerif Lite features an ABout Us section where Big Text is formatted on the left, normal text is formatted in the middle and 4 charts are shown on the right, as illustrated in the demo: http://themeisle.com/demo/?theme=Zerif%20Pro

This is a pretty nice way of formatting this section and in the previous version of my site I had the 4 charts deleted (as I do not need them) but I did have the big capital text and smaller body text formatted in the way as described.

However I have been updating my site, installing some plugins (SiteOrigins) and changing some more and suddenly for no reason the formatting of this About Us section changed. As you can see now on my site (www.debut-event.nl) I do have the About Us section enabled but the two paragraphs are outlined underneath each other instead of next to each other. Does anyone have any clue on why this is happening?

Thanks in advance!

Joris
