Unlocked Icons & Heroes disappear as selectable players in career mode.

Hi,

I have been spending a lot of time and was going to purchase FC points to unlock ultimate packs for more icons in career mode.  I noticed some of my previous unlocked players are gone after I unlocked more icons and heroes in season pass. 

Fernando Torres, veron, and kluivert icons are gone? Is this a bug?

if I’m going to spend time playing ultimate team and career mode to unlock icons i thought they would remain unlocked forever even in offline career modes.  

can you confirm if icons and heroes I unlock will remain unlocked and transferable in career mode? 

One suggestion that I hope EA considers is making the unlocked heroes and icons available as free agents in the offline settings.  So if I go to offline settings, trade players EA can make an icons and heroes free agent area so users have the flexibility to transfer their favorite icons to various clubs that they choose offline.  As a fan it would be even more incentive to grind in ultimate team and purchase fc points to obtain and unlock these legends. 

your assistance and consideration is greatly appreciated.

thank you
