Players dissapearing from the weekly private leaderboard

Hello everyone, i'm here to report an really weird bug that never happened before.

I have tihs private leaderboard for the steam players of alvanista.com website

Its set to a tsa score weekly and it always worked this way but this week pretty much everyone disappear from the list and only two remained , its a know bug ? Do i have to create a new ranking maybe ?
