XF 1.5 Profile Comment - Space missing


I seem to have an issue with profile comments not having a space between the person's username and the message container as seen in the image below.

I haven't noticed this issue before with the styling since our forum users don't post to peoples' profiles.

I'm stumped on where to go to fix this in the styling, so if someone could point me in what probably will be a simple direction, it would be much appreciated.
