STILL mess up subs in events?

Attachment 139635

At this point, I really cannot come up with even an absurd reason as to HOW one player on bench (at position S2) disappears, my GK who was supposed to be at S1 moves up to S5 and I have a 2* player in subs when I start an event match?

REALLY?! REALLY? How do you do that? Now the associations also disappear my sub and replace him with the next 2* player on my reserves? How are you ABLE to do that?
