have you checked the inputs from the directional switch?
maybe you have a switch that is slow/sticking causing the delay.
If when having the handset connected you see it telling you that both contactors are showing a signal then my first thought would be to check the directional switch circuit and make sure one switch is not sticking.

The only other thing i can think of would be the logic is defective.

just some thoughts to ponder since nothing else seems to point you toward any conclusion :o)
