You do not have a link list with a handle set to rzr-900-900-xc-s-900-s-1000, or you do and it's empty. Go ahead and create a link list called RZR 900 / 900 XC / S 900 / S 1000 on your Navigation page and populate that link list with links that point to collections, to see collections listed here. Make sure the link list also has a handle set to rzr-900-900-xc-s-900-s-1000.
