It seems some pre-patch Mythic+ action has leaked into the title determination of Season 3! Players have been receiving the 
Unbound Hero: The War Within Season Three 0.1% title from playing in the pre-patch, and Blizzard will be fixing the issue within the next few days. Only players who properly got into the 0.1% of TWW’s Season 3 will keep the title.
We’re aware of the issue causing some players to incorrectly receive the War Within Season 3 Unbound Hero title. That title is intended for the top 0.1% of rated players in Mythic+.
We will correct this, and it may take a few days, but afterward, only players who achieved the required M+ rating before the 12.0.0 patch and the end of the competitive Season will retain the title.
