Ram SS - Knee Brace on sloping slab (Ramp)

I am adding knee braces to my frame which is located at a ramp. For some reason my knee braces are attaching to my level and not my beam. The location of my beam is at a different elevation from my ramp level (I had to adjust column heights to create my ramp).

Do you know why my knee braces are attaching to my level and not my beam? Is there a way to correctly attach my knee braces?
