I've created a lot of challenges that I have posted in my geo club, but when I post them and people start the challenge, the leaderboard is broken until no one is currently playing it/they are all finished. For example: 2 people has finished the challenge, and I am looking at the leaderboard while a third person is in the middle of completing the challenge, the leaderboard is completely broken and not viewable until that third person is finished. I believe this issue is easily reproducible for devs to test. Image attached shows how leaderboard is viewed when someone is in the middle pf playing the challenge.

Leaderboard should be viewable like it is with any other challenge (for example the Daily Challenge) even if someone is currently in the middle of playing it.
