HELP NEEDED!!!

Hi,

I've gone and ticked a tick box that means when I move a player to my Junior Feeder club i no longer get to choose the details of the loan (length of loan, position etc) and it now just sends them out of a month and I cannot find how i can undo the tick box to allow me to select the details before they go.

How can i remove this tick and get the info back?

thanks
