Product review editing structure of text

Hello,
I cannot find any solution, please can you help me?
At the posted link is a view of an example item out of our shop with opened tab “Bewertungen”.
Scrolling down you will see the checkboxes and there the text is shown in a very small column.
How is it possible to change that into a normal text structure?

Kind regards,
Johannes
