Changing loco address on Dynamis

[Derek]

Hello,  I have taken the plunge into Dynamis, and I am slowing getting used to it.  I have come unstuck changing the address of one of my locos.  It was at address 7 and I tried to change it to address 8, but now I have loc 0009 on my screen while it still shows locomotive 7, and the unit does not move.

Is there anyway I can recover my position?  How do I know what address it is now?

Any help would be very much appreciated.

Many thanks,
