When doing SBC, players in work area removed

Don't know where to put this, but after already spending a considerable amount of money on getting my team to where I want it, amd grinding the sbcs, I've been left extremely frustrated at all players in my work area, when submitting the sbc have been removed, I use them in work area to see what ratings I need to complete the sbc, I've lost maybe 8 players, but the most noticeable, all untraceable are casemiro, odegaard, and Rudiger
