Why is there a difference between a player's "Team" value between the client and the server?

I'm just trying to make a simple script, or so I thought it should have been, and this script tries to access the

plr.Team

value, with "plr" being

local plr = game.Players:GetPlayerFromCharacter(hit.Parent)

Now, I've had a really massive issue with my script(s), as the client and the server seem to see the player as being on different teams. What I mean by this is that: I have two teams (Team1 and Team2) When I call a function to get the player's team on the server it always returns with "Team1", even if the Roblox leaderboard shows the player to be on Team2 However, if I call this code from the client side, It returns with the correct value.

I'm wondering why this is, and how I can fix it, as this would cause major issues for me. I've tried many things, such as trying to set the teams myself, but I've had no luck so far. If anyone knows anything about this, I would be very appreciative as this is really bugging me (excuse the pun).

I will provide my scripts here. These scripts are the children of the part that the player shall touch.

Script: isTouching

debounce = false
script.Parent.ControllingTeam.Value = nil
rechargeTime = 0.5
script.Parent.Touched:Connect(function(hit)
    if hit.Parent:FindFirstChild("Humanoid") then
        local plr = game.Players:GetPlayerFromCharacter(hit.Parent)
        if debounce == false and hit.Parent:FindFirstChild("Humanoid").Health ~= 0  and plr.Team ~= script.Parent.ControllingTeam.Value then
            debounce = true
            script.Parent.ControllingTeam.Value = plr.Team
        end
            end
        wait(rechargeTime)
        debounce = false
    end)

Also, I am quite aware this code is messy, I've just been experimenting with trying to fix the bug.

Script: ptsGiver

local delayTime = 5 --this is how long the script should wait before giving the team of the touching player extra points
local team = script.Parent.ControllingTeam
while true do
    if team.Value ~= nil then
        team.Value.Points.Value += 5
        print(team.Value)
        print(team.Value.Points.Value)
    end
    wait(delayTime)
end

Also, another thing that may be of use that I thought I should probably point out is that when I try to manually set the player's team value to Team2, it just doesn't let me and it comes up with Team1, no matter what I do.

If you need me to provide extra detail, let me know, and as i said beforehand, any help would be greatly appreciated. Thank you.
