Simple Catch Pro – size and alignment of sub menu boxes

Hi Sakin, I am working on www.timewisefoundation.org.uk and I have a question about the alignment of the sub menu boxes. If you see the About us sub menus, the alignment is right. It starts at the corner of the About us menu. However if you see the menu Our work and the other menus - the submenus are not aligned. Hope it makes sense, see attached screen grab. Can you please help? Thanks Poornima
