My gamerscore isnt updating, only with RYSE

Hi earlier today i completed RYSE Son Of Rome and was about to uninstall when i noticed i only had 515G in it, i then looked in my unlocked achievements and totalled up that i should actually have 780G, on my total gamerscore and the gamerscore for the single game ryse the totals haven't been updated. However when i snap achievements i see that the total for ryse is correct (780) however my total overall gamerscore still isnt correct. A fix on this would be helpful as i am losing a good 250G here guys :)

When I look at your TA profile it says you have 780 GS in it.

I realise this is late but I am having a similar issue although it isn't a problem. Just a matter of the xbox one not always showing when you have popped achievements.
