With the OP not being in the driver's seat every weigh-in, it is a little difficult determining what is going on, but here is my attempt:
Assuming that the OP was standing on the front scale section, and both the axles and tongue of the trailer were on the 3rd section when the trailer was unhooked, the hitch weight should be 840 lbs. (truck 2 axles total with trailer hooked up without WDH bars minus the truck 2 axles total without the trailer hooked up). If the WDH bars were in back of the truck, you can subtract about 40 lbs. or so from the 840 lbs.
Again, assuming that the OP was standing on the steer axle section during the weigh-in without the spring bars attached, the spring bars are only transferring 100 lbs. to the steer axle, and 60 lbs. back to the trailer axles, reducing the drive axle by the resulting 160 lbs.
IMHO, that spring bars need to be tightened up quite a bit to bring the steer axle back to near the unhitched weight.
Kudos for the OP weighing his combo and wanting to get things right !!
Getting the WDH dialed in correctly will make a world of difference with the handling of the unit.
