I have the same issue with two achievements in Forza Horizon 3. I’ve met all requirements of the achievements and my Ingame stats prove that but both are stuck on 94 and 93%. I spoke to Microsoft twice regarding these and they was useless, just kept telling
me to post on forums and wait for a reply from a “specialist achievement team”

When to pop like that it a glitch. It not same glitch you thinking. This kind glitch either pop early, Pop late or wrost it never poped at all. Go to your XB1 and compar to me. Some achievement at stuck at 93% on one achievement. And on 96% on another achievement
on warframe. And on the one. There is sever glitch. That takes days to unlocked the achievement in said game.

Having the same problem with the Batting 500 achievement. The tracker is stuck at 93%, but I got the in-game achievement for finishing 500 bounties, but it won't pop on the xbox achievements. Pretty demoralizing to put in the grind for that many hours, to
have the achievement glitch out.
