If you set the Team as “Current” and Players as “Auto”, everything works as it should; only players in the assigned season and Current Team are displayed in the list.

However, if you set the team as “Current” and Players as “Manual”, players show up who should not be there. (they should be hidden behind the “Show All”.

Current + Auto should display the same data as Current + Manual.

At first look, this appears to be happening because the Manual filter is is only look at the “Current Teams” metadata and not the Seasons.
