If you go to the players page, you can either find players by searching by name, or filtering by Top Players (either All or FA only, additionally filtered by All positions or a specific position).
If you search for players, all players will be shown with a Week 1 projection of 0.
If you filter any of the available filters, it will instead show their actual Week 1 2025 stats instead of their Week 1 projections.
The week 1 projections are definitely available, as you can see them from your lineup page, or from your matchup page, so this is likely just a UI bug.
As an aside, it would be nice if we could see a player’s projections on the matchup page. Currently, you can see the total projection for the team, but not each individual player’s projection.
