Formatting of BuddyPress Login Widget

I have recently created a new sub-domain at
For some reason the padding is too big (top and bottom) of the BuddyPress Login Box in the left sidebar.

I can't understand this since I have set all the Customizations for the layout to be identical to the other sites, and I have copied and pasted the Custom CSS from one of the other sites.

See screenshots to show "right" and "wrong"

Would appreciate your expertise.
