1st make sure the small rubber hose attached to the water level switch is not pinched or kinked at any place along its length running from switch to tub.
Next I would blow into the hose down into the empty tub to make sure it flows air freely.
If the hose is clear, carefully adjust the small 1/4 inch hex head screw on the back of the pressure switch. I would start with a half turn clockwise and then fill tub on Super to see if it lowered the level enough. If still not where it should be, then adjust accordingly.
