Q&A not displaying properly

I installed qa plugin and when clicking http://twojeflp.webd.pl/aloesnacodzien/questions/ask/
The plugin's frontend is dizzy (screenshots) I copied php file into my theme folder for some customisation. But can you tell me if that's a usual way it's been displayed at the beginning or it's not normal.
Could I get any help with organising the way it looks before digging into further customisation?

p.s. Just as a suggestion, maby it's worth to change the way of integration with a theme. Many plugins use shortcodes so you can display their content in any page you want....
