Designing an app feature that lets a group of users register for multiple accounts in certain situations. The 1st screen shows that 4 users, who are in the system, and 1 user is already registered from a previous session. After user 1 has been registered user will return to the 2nd screen where user 1 is no longer able to be selected.
My question is does the order of these options make sense. should unavailable options stay in their current position or should they be pushed below?
