How to delete Game data progress on Apple TV so I can replay the game?

I downloaded and played "Horizon Chase" on Apple TV.

I would like to delete all its data so I can play again from the beginning.

First I deleted then re-downloaded it, the game still has all the races I've played.

I tried to delete from iCloud but it doesn't show there.

(I went into iCloud - storage - manage - shows other games but not Horizon Chase.

Please help anyone
