Your Gan Ning card must be showing 1/2 star. You need to summon him twice (after you get his card in first place) to get 2nd star. The next time you summon him again, his gonna be 2nd star.
2 star = 2 times summon (after getting new card)
3 star = 3 times summon (from 2nd star)
4 star = 4 times summon (from 3rd star)
5 star = 5 times summon (from 4th star)
