That will clear the look of it but because of this issue you might want to check if it’s still works.
I’m afraid thats not got anything to do with bbPress so there’s not a lot we can do to help. Given that the code is output, its probably jsut a styling issue, which really is something you can find out at any of the CSS websites on the interweb.
Additioanlly, you have paid for theme, so you should probably ask there instead of here, given that your bbPress works 
Oh go on then, because I’m being nice…
Right, if you open up the source of your webpage in a browser, you’ll see some hardcoded (awful idea) CSS into your WordPress page (line 70).
Just copy that into your bbPress forums, and it too will look the same:
And really bro, if you pay for a theme and then it doesn’t look like the way you want it, go ask at the forum of where you bought the theme
