Heroic: The Voidspire

For some reason I have killed all the bosses twice now and Lightblinded Vanguard are still greyed out....

My statistics page has 2 confirmed kills of the bosses aswell.

I submitted a ticket fingers crossed they help me out

This is still bugged on vanguard. Blizzard has yet to answer my tickets on it. So it looks to be an actual bug that they are ignoring

Hello,
I am writing to report a bug regarding the Heroic: The Voidspire achievement credit.

As shown in the attached screenshots:
My in-game achievement window does not credit me for defeating the Lightblinded Vanguard, while all other bosses are checked off.I have attached a screenshot of my logs confirming that I did indeed defeat this boss along with the others on Heroic difficulty.

I also earned the Midnight Season 1: Champion of the Dawn achievement yesterday, further proving that I cleared the Heroic raid content.
But i have all achivments, something desnt work properly. I didnt get achivment for 3 bosses, and for 2 bosses. I dont know why
Since this appears to be a tracking bug, could you please verify my logs and manually grant me the Heroic: The Voidspire achievement?
Thank you for your help!
