Hello Blizzard,
i Finished Season 3 in open Role with master2.
But now in Season 4 it shows me that I have finished open role selection with Diamond 1.
Also, I only got the Diamond reward and not that of Master. (I am now also missing the title "Master Challenger).
Can someone please fix this?
Same I hit gm and finished gm but yet the give me only master comp points and title like tf did I grind to gm for?
I literally went from gm to DIAMOND 
Same with me, reached Masters but got diamond rewards
