How to move a form in register page

Hi there,

I`m using holder buddypress and modified register.php
As seen on picture, I would like to move on the left (above Username) the form (and delete Name) currently on the right. Same thing for the "sign-up" button to move on the left.

Do you know how to do? The code is different from other form and don t know what to do

I have granted an access to my site, so if you could help me, will be great.

Thank you
