clone command doesnt work well with pressure plates

i was going to have screenshots, but its kinda hard to show. plus it would take like 5 screenshots or something. but i was gonna make a device with the new clone feature, the move part. and i would activate the command with pressure plates. i noticed that cloning towards the +z axis, the pressure plate wouldnt come back up. it would be stuck in the pressed state fore ever. but on the -z axis the pressure plate will come back up. this is obviously a bug. though im not sure which one is the bug. im assuming its the +z axis, as it doesnt ever come back up. please say if im lacking information. thanks
