It seems weird, I know, but it is intentional.
Since there are so many events in the ToW (24 per day across 20+ days), this temporary filter is there to only show ToW rides and let you find the stage(s) that you’re looking for at the time you’d like.
Unlike the other EVENTS filters, it’s not an option that most riders will leave ticked throughout the ToW period, but only toggle it on when wanting to plan their ToW rides and then untoggle so that the rest of the events are visible again.
Without the ToW filter, finding rides 3 or 4 days in the future means the endless scrolling and waiting for Companion to catch up that we know and… love.
