I don't see any way of getting a new duty officer out of reserve (I want to add them to the crew). I see only a "dismiss" button but I think that would just make them permanently unavailable.
Reserve is your crew. To take them out of that, go to the Space and Ground sections under the roster and click the < arrows to assign them to the active roster, which is limited to 5 space and 5 ground right now.
Assignments draw from your reserve roster, so a doff you want to use on assignments doesn't go in your active roster. Also, some doffs (civilians and a number of science specializations) can't be put on the active roster and are just for assignments.
