Ideas
I don't know how this happens but after searching far and wide there are only 2 stunt/slam challenges today in the daily challenge refresh while the daily task would need 4 of them? I'm at a loss here.

Our team is investigating this issue. As a workaround, you can do 2 goals in a challenge, then exit, then do another 2 in the same challenge.
We know that if you already have completed the challenges this doen't work for you. The team keeps investigating this.
Sorry for the inconvenience.
Same for me, finished all of today's Stunt Challenges and only 2/4 progress on the daily task. I even did them multiple times, tried also some stunt challenges from the season, none of them count towards the remaining two.
