What's wrong with this scoreboard

[Mc28]

every 20 tick:
    loop all players:
        if {scoreboard.%loop-player%} is true:
            wipe loop-player's sidebar
            set name of sidebar of loop-player to "&e&l◈ FUN ◈  "
            set score "&e&l▶ &b&lnickname " in sidebar of loop-player to 9
            set score "- %loop-player%" in sidebar of loop-player to 8

            
command /sb [<string>]:
    trigger:
        if arg 1 is "on":
            set {scoreboard.%player%} to true
            message "scoreboard on"
            
        if arg 1 is "off":
            set {scoreboard.%player%} to false
            message "scoreboard off"
            wipe player's sidebar

Only one user's information is displayed on the scoreboard of all users
Can you help me?

Every 20 tick, not recommended.
SkRayFalls scoreboards are bad, SkBee or Skore are good.
