Problem to change association with Dimmer

[omale 0]

I've made an association with a Dimmer (FGD211).

The Dimmer #10 has two bi stable switch.

By default the left switch activate the light 1.

I've made an association to Group2 to activate the light 2.

The problem is that I can't change the association of the group 2.

It's more or less the association of the Group2 can be done once.

If the association is made for Group1, there is no problem. I mean I can change the association as I want.

Is it a bug of the dimmer when association is set up for bi stable swich ?

The problem was only to reset the configuration of the dimmer.
