That's exactly what you want. I assume you are puzzled as to have the front an be back to original height, yet the rear is not back to original height. The answer is that not all of the TW is transferred to the front wheels. Because of the way a WDH works, some of the weight is also transferred back to the trailer axles.
By lifting the bars, a very large torque is applied to the hitch head (and therefore the truck's receiver). This transfers weight to the front wheels. But that force lifting the bars has to be supported by something. That something is the snap up brackets (or L-brackets, depending on your WDH), which is on the A-frame, 2-feet behind the ball. That load get's to the ground thru the frame, to the axles and wheels.
So, if you were to measure all axle weights before and after engaging the bars:
Rear axle wgt decrease = (front axle wgt increase) + (trailer axle wgt increase)
The main point is that your front height is back to stock, which means your front loading is pretty much back to stock. IMO, you have a perfect setup.
