Disappearing gamerscore

Logged into my profile on my xbox one today and noticed that my gamerscore is only reading out at 2140. It was previously well over 120000. I went to view my achievements and saw that all of my xbox 360 games said that i had 0%, whereas before i had 100%
on most of them. My gamertag is . Thanks for any help you can give.

Disappearing Gamerscore

This is happening to me as well

 

Disappearing Gamerscore

On Wednesday 21st January 2015 I had a Gamerscore of 182,995, and started playing The Walking Dead Season 2 on Xbox One, I finished this game a couple of days later, and got the full 1000gs, so my score went up to 183,995gs, however, the next day when I
went back online 270gs had disappeared, leaving me with 183,725gs, I was told by a friend that if I unlock an achievement on another game that this would fix the problem, and lo and behold it did, however, today (Saturday 24th January 2015) I played and finished
a game on the xbox 360 (monopoly deal) to take my score up to 184,995gs, however for some reason it has once again gone out of sync, this time by a greater amount then what had previously disappeared, I should be on a score of 185,025, as after completing
Monopoly Deal I started Walking Dogs Definitive Edition and have earnt 30gs on there, however my Gamerscore is now showing currently as 184,595gs, which is a deficit of 430gs, the worrying thing this time is that I have started another game to try and right
this issue it hasn't done so this time, does anyone on here know of a way to fix this, as it's starting to get bloody irritating!!!!

I have actually gone through my entire Gamerscore and added it up and it does all add up to 185,025gs so no actual Gamerscore has disappeared, the weird thing is that also on
www.xbox.com when I checked my Gamerscore at the start of the day it was right, then for some reason it drops on there too.......any tips on how to fix this would be greatly appreciated, I also track my Gamerscore
on websites like trueachievements so I know exactly how much I should have, I just can't work out why this keeps happening recently.
