I select an activity and all devices are turned on and set correctly. Later I pick up remote to change a channel or volume and I am at the main Activity Menu again, and Day and Time in the display are wrong. If I choose the same activity it tries to turn the equipment on again. I have to leave the room to get out of IR range, choose the Activity again, then return to change channel, etc. I need to re-program Harmony One via USB to get the Day and Time reset. This has happened 5 or 6 times in the last few weeks. What gives?
