Start a new game in MLS.
Go to Dev Center.
Whitecaps academy doens't have staff listed. If you go to the Staff tab, it's only the B team.
If you go to the b team and again go to the staff tab, it will list BOTH the B team and Academy team. But if you select the academy it just goes to the Roster screen.
Pretty sure the inability to see Academy staff was logged last year.
