LGB EPL control box

Just installed new control box for two 2 switches, running off accessory from train transformer. The problem I am having the switches throw only in one direction . Moving controller button in the opposite direction the switches do not return. Any ideas greatly appreciated
Thanks

Be sure to use A/C power, the 5075 box has diodes to polarize the output for throwing the switches.

Thanks for the help was using DC power.
