If you've not tried lowering the top section of the vertical just a bit I would. It is favoring channel one, which indicates the best match may likely be below that frequency. Shortening the overall length of the vertical should bring it in nicely.
How much? Can't say, but I'd probably start with 3", and see where it lands.

Exactly. "Measurements" that somebody in another location takes might work perfectly well for him and be out of the park for you. This is where an antenna analyzer would pay for itself. If you don't have one, experiment. Try changing dimensions a little bit and take notes about what happens. In general, the longer the antenna, the lower the frequency at which it'll show the lowest SWR.
Some stats about what you have tried would help with analysis!
If you have used the measurements that are in the manual, there's no wonder your having problems.
As stated up stream, the swr your seeing is better then some stations out there.
I've had two P500s and both of them were over 22 ft.
