Wordpress/buddypress child them CSS Alignment issue

Hi, I just built a child theme for buddypress / wordpress and made some customisation on the template , but there is CSS alignment issue which I don't seems to get. When you are viewing your personal user nav i.e activity, profile, message, album etc, all the content align properly as I want, but when you are viewing user nav of your friends all the content moved up too much and don't align properly. And you will also adjust some css in the activity stream. Generally all is CSS issue to my knowledge. Please ask for the site URL so that you can view the problem.

Please only bid if you know you can fix CSS issue . No tester please.

Thanks
