Destiny Flawless Raider Achievement not unlocking.

I am having problems with the Flawless Raider achievement on destiny unlocking. I ran the Crota Raid with my fireteam on January 7th, 2015. Upon completion of the raid and doing what was required only one of our team members received the achievement. I have
already chatted with someone in xbox support and ran through all of the troubleshooting without any success. I was then redirected here. Here is a link to my Bungie profile showing the recent raid that I completed.

As you can see we completed the raid with zero deaths. The only person to have the achievement unlock upon completion was Ghostly x Wolf. A few others had the achievement unlock the following day on January 8th. My achievement is still showing locked. I
would greatly appreciate any help with this.

Flawless Raider achievement not unlocking!

I've had problems with a couple of the achivements, but then one day four or five just popped up when I was starting the game, it may just be that.

 

Flawless Raider achievement not unlocking!

Some friends and I ran a flawless Crota's End raid on 1/5/2015. As soon as Crota fell, the achievement popped for all 5 of my friends except me. I have waited over 24 hours and still have no achievement, but when I compare my game with someone else's,
it says my achievement percentage is at 94% (only Flawless Raider is missing) while my Game Completion percentage is at 100%. I don't know what to do to fix this. Not only do I not want to go through another flawless raid, but I don't want to do it only to
have it not pop again! Here is my information in case anyone can help. I finished the raid between 10:30 and 11:30AM Eastern US Time on 1/5/2015. I completed the raid with a friend named Voice of Enigma, and his achievement unlocked immediately (so whatever
time he got the achievement is the same time I should have gotten it). Can someone please help me?
