achievement point not added to total gamer score

I recently played Mass Effect 3 on my Xbox One and got 500 points as achievements, I can see those points in my profile. But those points are not added to my total score. I started playing another game after that and points from this game are getting added
to total score but points from ME3 are still missing.

My Gamer tag is .

Inconceivable! not unlocking

Nevermind, the problem solved itself.

This had happened last night with the game saying i did not get the achievement, and upon checking after work tonight, the achievement was unlocked and the score was added to my overall total.

 

Achievement leaderboard issues

I've noticed over the last week or so that my achievement score has steadily been declining even though I've been getting achievements regularly. Trying to make some sense of this, at first I thought it had just stopped adding my 360 achievements, which I have gotten well over a thousand gamer score in the last couple weeks. Yesterday I got 2 new achievements in Titanfall on Xbox one worth 60 points, they weren't added to my total score. The only game that is currently being scored for me is Sunset Overdrive at 155 points total for the last 30 days. I have actually gotten more than 600 gamer score in Sunset Overdrive in the past 30 days but only those 155 are showing up. As I stated, I have acquired around 1500 more points on both 360 and Xbox one in at least 7 different games combined on both platforms. Anyone else having this issue? I have friends who don't have Xbox one that are being scored ahead of me so I can't make any sense of this. Thanks to anyone who might know anything about this.

 

Are you sure it didn't count the 500?

For what it's worth, I quickly ran through your public profile and the totals of your Gamerscore for individual games, including ME3, and it came to 12,575G, which would appear to be correct.
