Unalignment in BP Corporate Theme

Hi,

My BP works with Corporate Theme.

On some pages of my website, there is a problem of unalignment.

Ex1 : When I want invit members to my group, the check box with friends list is not on the center column, but it's hide under the right widget.

Ex2 : When I want edit my group, I have the first tab with "name", "description" and "recent news". Betwen "name" and "description" I should have radio button "yes" or "not" without comment. It's "not" by default. When I swith "on" value, it changes anything and the value automaticly switch "off". But I don't know the fonction of that option..

Edit : sorry, the subjet is in the wrong catégory, please, move it.
