register player

In football manager 2015 i am playing with benfica and there i have the option to register players but when i move to b time (benfica b) these option is not there
i stop in the last they for registration because i need some players that i move to benfica b to play in my first time if something is going wrong. in fm14 i had no problem. can somebody help how to register a player in b times?

Have you tried moving them back to the first team?

the problema is that i can register 30 players in benfica the others i changed to benfica b to register them there. in liga portuguesa i can play with the players in both times if they are registered. so in benfica can play with the players that are registered in benfica b. but in benfica b i dont have the icon tho register the players. dont know if is a bug, because in fm2014 i did that and play with 30 players registered in benfica and 30 players registered in benfica b. so i had 60 players to choose.
