characteristics not aligned horizontally

hi,
as attached in my photo the characteristics are not aligned horizontally. I looked at the code and I mentioned that there is "br" after each span. it is in the file administrator\classes\filter.php
can I align them with css? and should I override the class file?

I forget also to mention that the price also is not good, I want to delete ":" and the price is not well displayed
