Challenge Progress not going up?

Doing private horde with a party and started at 0/200 waves completed for Studios Horde Challenge. The progress updated through 24 waves but then stopped. We went to 30 and got booted because the servers took a dump… Now we have gone through wave 25 and the challenge counter is still stuck at 24/200…

Is this normal? Will this update later???

Update: Ok, just tested this out. Website (https://gearsofwar.com/en-us/my-rewards) wasn’t showing progress but then I went to the achievement tracker on my xbox, it was correct. Once I viewed that, I refreshed the website and it was correct. Hope this helps!
