All Tradeable Players Sold On Transfer Market And Some Disappeared

I played Fc 26 ultimate team yesterday and my team was completely fine. But today I opened it all of my tradeable players were sold on the transfer market and I had 17,000 coins with a few players missing from the club like Cristiano Ronaldo. I don't know if this is a glitch or if someone has hacked my account. If you can, PLEASE HELP.
