Double Player & Retirement Bugs

I don't know if thess are bugs but when i get a player from another team why do they still play for the ex team. For example i'm coaching Essendon and i got Taylour Walker but he still shows up playing with the crows and when i'm versing Adelaide there is 2 Taylour Walkers.

Also i've noticed when it says a player is retiring or retired why do they still play.

(Note: these bugs are both in coach career mode)
