Thhanks Niko for sharing your experience with me. I did not find a reason why this takes place so I ran a separate 600 foot Beverage about 50 feet away and parallel to the two wire. The single wire works fine on 40 meters to the direction of the termination. A possible reason why the two WD1-A does not work in the reverse direction on 40 meters, but works well on 160 and 80 could be that it is to long for 40. This is just a gut reaction as I have not come up with any reason.
I hope someone of the topband list group here has an answer.
