[SOLVED] Automatic assignation in activity from Kanban

Hi,
I'm on a 11.2.2 version

I activated the option "when i affect a responsible to on activity, he become as well assigned with the expected working time. It's works perfectly on the activity list.

My issue appears when i use kanban. When a member drag a card on the column "en cours", a window ask for the responsible. When the member select his name, he become responsible but he is not assigned to the activity.

If i select "modify" on the contextual menu of a card, and i select the responsible, it's ok and the responsible become assigned as well.

Is there here a limitation or a bug ? Thank you for your help

Ok, I found it !

I had to change some habilitation
