Issue with adding playable league?

I've just been sacked by a club in the Premier League and decided I wanted to go to Sporting CP,

Used to editor to sack their manager and couldn't find the job on the adverts.

So I realised it's not a playable league so I added it as a playable league and it still didn't show on the advert list,

So I used the editor to move myself to the club and it wouldn't let me saying i can't manage a "inactive club"

Anyone know what to do?
