Digigrax forgets loco on left side of DT402R

[TinyTrains]

This not the end of the world, but just strange. When I shut off my system lately, the loco assignment on the left side of the DT402R is blank when I turn it back on. It used to always be there. Throttle is plugged in with no battery. The lead unit is still on the right side. There is no other activity between shut down and power up.

Anyone else seen this?

Thanks,

Mine has done that when the left address is consisted to another address.  Try adding an independent unit to the left side, and trying again.
I have also noticed when I unplug my throttle and plug it back in, the left side is what it defaults to, and the right side has to be selected.

I have seen the loco switch sides too. It is just odd, because it did not used to loose the left side, and I have made no changes.

Thanks.
