I'm not 100% sure, but I think that what you have to do is leave empty squad spaces (assuming you don't want to register reserve/youth players like manchesterblue97 said). For example, if you need four homegrown players out of a 25 man squad, but only have two, if you pick only 23 (including those two homegrown players) and leave the final two spaces empty then it should work.
Still, if you're gonna have to leave it empty, you might as well pick a youth player instead, just in case you need to use them!
