I can’t Find my players, Gullit, Lucio, Di Nitale…

I can’t find or use my players in my club for training like Gullit, Lucio, Di Nitale, they aren’t showing up with my other players on the training menu. 

And why can’t I sell them on the transfer market either? I can “purchase” but the “sell” option is grey, why?

I can’t sell my TRADE-ABLE Gullit I bought with my own coins? I can’t use any of them in training (gullit, Lucio, Di Nitale) ALL I bought with my own coins but can’t use them and I can’t use any of them for player exchanges!? Why are they just sitting in my club?  

I’ve tried unlocking them, locking them, putting them on my bench, putting them in reserves and nothing. 

someone please🙏let me know what’s going on….
