The car call for bottom landing wont latch from c.o.p, will latch from controller UIT, but not the rocker switch in controller. The top call works from rocker switch. The bottom call will latch on Fire service. The door open button also will not work when at the bottom landing as well. The door open button will only work if I use it prior to getting a full close only at that floor. It has to be a problem is software. Still curious what wltr00 did to fix issue
