Mfx locos continue to drive after throttle set to 0 kmh

HI,

I have an issues with some Mfx locos.
I'll start with the first issue:
After programming successfully as Mfx on the programming track, they run on the main ok untill I go to stop them, where they will continue to drive slowly with the throttle set to 0. Only way to stop this is to turn off the Commander and reboot (shutdown).
Any suggestions?

Regards,

I resolved the issue, all is working properly.
I had improperly set the addresses.
Beginners mistake!

Cheers,
