Buddypress space between profile tabs

Hi again,
I am working on my profile page, you can go here and select any member to see how it looks. I have made the changes kindly prescribed to me here where I place images as background for profile tabs. And its working but there is space left between the icons, how do I get rid of the space and make it look normal. This is the space I'm talking about:

Thanks,
Mwale
