Not receiving rewards in event quest

Running through classic and the rewards it's shows I've earned at the end of the run isn't going into my stash, isn't going anywhere lol.

I posted the same thing, but figured it out, basically it's just showing you a milestone you have to reach, the stones at the side that says 24/30 is the milestones you have to reach to collect the rewards.
So in the picture you see 21, you have to collect 21 stones to get that reward and 24 should be the last lane for Mr Knight aka Moon Knight.
