I've got a similar setup. I'm thinking airbags will help with the bounce, but may try adding a washer as per above.
One thing to note is that your tongue weight is a bit more than the weight added to the truck. I weighed my trailer tongue, not hooked up, just the tongue on the scale, at 1050 (480KGs) but find that all hooked up, it only adds about 800lbs to the truck with some of the tongue weight transferred to the trailer.
So where you show your tongue weight around 620, you may find if you just weigh the tongue, it is 800 or so. But 1K basrs still sounds right for your setup.
You measured tongue weight the proper way, directly on the scale. When hooked up to the truck, including engaging the WD bars, some of the weight on the truck's axles is transferred to the trailer, but the tongue weight remains the same.
When the OP hooked up the trailer without the WD bars weight was removed from the front axle and added to the rear axle. None was transferred to the trailer. Once the WD bars are engaged weight was transferred to the front axle of the truck and back to the trailer axles. The tongue weight remained unchanged.
Your WD bars are adjusted about right. The weight on the front axle is the same, within the error of measurement, as it was originally. I would find some way to increase the tongue weight and then readjust the WD bars.
As long as you are working with the actual weights you can ignore the measurements at the front axle as it is lowered and raised by the WD bars. They are an approximation for the better way of actually measuring the weights on the axle as the WD bars are adjusted.
