Line break doesn’t work

We use the Theme Happykids because it’s looking nice, but one thing we can’t get it working fine. The line breaks.

We use the CWS builder to make some text blocks with a lot of text, and off course we use some line breaks in te text, but this doesn’t work like it should be. In the text/Visual editor you see the line break and it looks good, but when we go to the website the line breaks are gone.

I have tried to add
in the text editor, different kind of returns (shift return etc.) but my line breaks don’t work. Any idea’s? Example you can see www.sinterklaas.nl
