Move to Train command issue (in TANE)

I am using this command on an airfield to switch the driver (captain) from an airplain to a push-back vehicle; once the airplain is pushed back and returned to it's parking space, I let the driver switch back to the Airplane.
This works, but there is one problem: after switching the Move To Train command disappears from the Driver Rule.
I want to repeat the rule, but because of the loss of the command, my air traffic cannot be pushed back again (and over.....).

Anybody any solutions ?
Thanks

Shot in the dark, have you tried deleting the command completely and downloading it again. Peter

Same problem for me (T:ANE build 88364).
This is a built-in command, it cannot be deleted and reinstalled ...
I did a try with <kuid:354694:60004> UZ Move to train : no luck ...
Those commands are encrypted, we cannot access the code, so the only workaround I found is to use <kuid2:57145:81110:1> Move To Train At Trackmark
With Move To Train At Trackmark, the command is still present after repeat.

Is this a bug ?
Thanks
