rsm 130 rear sump question

The rear sump of my RSM 130 is level with water across all chambers with no movement.

My question is, behind the gate (1st chamber) shouldn't the water have a "Waterfall" effect dropping water down into the chamber from the display section of the tank?
I have a Media rack set up behind the gate and water just sits at the top of the rack. no movement.
No matter how I adjust the gate up or down, the water level does not change in the back.

Shouldn't I be seeing some downward flow into my media rack?
Or should there be no movement at all?

All pumps work and have tunze 9001 skimmer attached to media rack in rear.
