current through the switch when the switch is open

Hi, i was trying to simulate a 4 bit adder with circuitlab, but when i got all the switches open current still get through the switch.

here is the link to my circuit: https://www.circuitlab.com/editor/#?id=6248teq76yq6

Sorry, too complicated for me to get a quick idea as to how this circuit works. My suggestion is to build the smallest element that contains the error and post again. Also tell me what measurement expressions you used in the simulation, i.e. how do you measure this current that should be zero?
