Does Prestashop think on it’s own? Critical problem - any idea?

[Flux Print]

Hey guys,

my problem is that wherever I create any tag, image or line of textin editor Prestashop ads "br" tag to every line. This "br" tag is not in my custom code and it's messing up my whole structure. There's no soft or hard return(eneter brake) on the end of each paragraph or any tag. Prestashop just inserts it in for some reson. Any idea how to remove this problem? Picture with problem highlited attached. Please check my source code on my website and let me know. Thanks for your time.

Peter
