RRS L-Plate and Pro Loop Strap

Hi everyone!
Good to be back home and good to get new toys. But sudenly I faced absolutely unexpected problem - when I'm mounting L-Plate to D70 with attached pro loop strap, the strap seems to be bit thick and it makes some angle and L-plate isn't mounted absolutely stright. Any thoughts?
