Silver RB and QB upgrade Set HELP

So i was checking out the silver rb and qb upgrade set where i collect 5 silver rbs/qbs and 5 silver trophies for each for a gold rb/qb and a gold trophy. So I clicked into them and dropped a couple players and trophies into each and pressed next, hoping to complete the sets later on. Now all the players, trophies and sets are all missing!!! And I'm not even done the set!!! What the hell?!?! help?! The players and trophies i put in are all gone and the sets are gone as well.
