You apparently don't understand how to set up a WD hitch. Before you begin, you must have a tongue weight scale or use an alternative method to determine your actual tongue of the wet and loaded trailer. Then when you weigh the rig, it should be with a 3-pad truck scale that will give you separate weights for the front axle, rear axle and trailer axles.
First step is to adjust the spring bars so about 50% to 60% of total tongue weight is on the rear axle. After you achieve the correct setting on the spring bars, then don't mess with the spring bar adjustment again.
Next step is to adjust the angle of the head of the hitch so approximately the same amount of tongue weight is distributed to the trailer axles and the front axle of the tow vehicle. If 60% of the tongue weight remains on the rear axle. than about 20% of the tongue weight should be distributed to the trailer axles and another 20% of the tongue weight should be distributed to the front axle of the tow vehicle. So the ideal final weight distribution should be between 20-60-20 to 25-50-25 percent.
So obviously you must know the tongue weight before you begin to fine-tune-the weight distribution. Then you must weigh the rig with the spring bars disconnected. Then connect the spring bars to about the setting you think should be close, and weigh the rig again. Then compute the percentages of weight distribution.
Example with a trailer that weighed a bit over 4,000 pounds.
Tongue weight = 650
Weight without spring bars connected:
front axle = 3040
rear axle = 3880
trailer axles = 3480
GCW = 10400
Weigh with spring bars tightened:
front axle =3280 = +240 = 36.9% of 650 = too much
rear axle = 3520 = minus 360 pounds distributed off the rear axle, leaves 290 pounds on the rear axle = 44.6% tongue weight on the rear axle = not enough.
trailer axles = 3620 = +140 = 21.5% 0f 650
GCW = 10,420 = 20# scale error caused by rounding.
So ignore the 20# scale error. The spring bars are a bit too tight because too much weight was removed from the rear axle. The percent moved to the trailer axles is about right but way too much was moved to the front axle. So back off a notch on the spring bar adjustment, and tilt the head a bit to result in less weight being distributed to the front axle. Then weigh the rig again.
If you're no better at estimating weights than I am, then it may require several trips across the CAT scale before you get the adjustment down pat.
Remember the goal: Distribution of tongue weight between 20-60-20 and 25-50-25 percent of total tongue weight
