Deadlight achievements not syncing

So I got error code 0x87c40011 yesterday on my Xbox One achievement app. This was the one that happened at Christmas. I played two games during this time; Deadlight and Ori and the Blind Forest. The error code is now gone today. I had played Deadlight
before Ori so I didn't realise the issue until then.

The Deadlight achievements "popped" at the time but when looking at the achievements the list shows 0G, 0/30 but when you click into the game it will show the five "unlocked" achievements and the date they unlocked.

The Ori achievements have synced fine.

I didn't play my 360 at Christmas so I don't know if this will fix itself, but has someone else encountered this and what should I do? I've already tried deleting my profile and redownloading it but no luck.

Achievements not syncing

Hi again!

The time is usually very short but if not I would leave up to 24 hours before contacting support about the issue. I tried researching this issue but I haven't found any solutions yet!

Your friend,

I found a solution. Thankfully, since I had not yet completed the game, all I had to do was unlock another achievement and the other ones synced
