Explanation

This will prevent a player shown in 2 handlers (example a player shown on the staff list but also shown on the global list). You must set the groupName same for all handlers you want to prevent the duplication.

If the player shown on the wrong tablist, you can change the priority. Higher priority means the player will be placed into that handler first.
