This will also solve this issue:

List of choice with item already taken

Hello Guyz, As you can see i have choice list with color (color are from another tab), and i can join my league (ligue Bibi). In the ligue i chose (ligue Bibi) Blue is already taken, then i would like to withdraw it from the color list. Do you have any idea? [TEst2]
