Clear Movement Trail

I am trying to make it so the movement trails on all pieces are cleared each turn. I can do a CTRL M when selecting the pieces, but when I try to do GKC or an action button, it doesn’t work. What am I missing?

A general mistake may be, you didn´t resetup the map/counter.

The biggest disadvantage of Vassal is, every new main change in the module works only with a new or a resetup of the map and counter.
