Editor Issue

I've spent loads of time putting a load of legends at their clubs and not all of them have worked, any ideas? I think it's the ones that had jobs already, on my editor they're where they should be but if I start a game they are just retired people.

Thanks

P.s. I just clicked on Lampard, who is showing as retired, and in history summary the current season says chelsea but he's just a retired unusable.
