Mission board not showing all available missions?

Issue Description:
Mission board does nto always show a mission of every difficulty. Today on a mission ending two “new” ones appeared.
Only one was a new mission, the other one was 2/3rds of the way through its playable time. Is this why I cant find all difficulties because the board is populated with missions in a certain order and additional missions are being left off of the UI?
