Why does a match show "Tour N" or "TBD" instead of a date?
A match shows “Tour N” or “TBD” when the league organizer has not set its date yet, the match is already open for predictions anyway.
In predictions tournaments based on an internal Playbox league, matches appear in the feed as soon as the league schedule is generated, even before kickoff times are assigned: instead of a date you see the matchday label (“Tour 2”) or “TBD” if the tour is unknown. Undated matches are listed after dated ones, ordered by tour.
You can make and edit your prediction right away; an undated match does not lock by the clock, it locks the moment the organizer actually starts the game. When the organizer later sets the date, it appears on the match automatically and the normal kickoff lock applies.
