Player Disappeared after opening a Pack

Last night around 11 PM UK time, after I finished playing Weekend league I was opening my 84+ Player Picks, I accidentally picked a duplicate option (Guiri) on my second player pick who I already had in my club. I decided to place him on 86+ Hero Player Pick SBC instead of selling him for 0 coins. Then after I finish completing the SBC my last 84+ player pick that I was rewarded from the weekend league disappeared. I would like a compensation if possible.
