Kick script is kicking myself?

I have an admin GUI stored in server storage, to keep it safe from exploiters. When a player joins, my system figures out the roles, then clones it into my gui. In that admin GUI, there is a simple kick script. (The event is in the GUI)

script.Parent.RemoteEvent.OnServerEvent:Connect(function(plrName, Reason, returnPlr)
	plrName = tostring(plrName)
	Reason = tostring(Reason)
	local Success, Error = pcall(function()
		local plrID = game.Players:GetUserIdFromNameAsync(plrName)
		
		local plr = game.Players:GetPlayerByUserId(plrID)
		if plr then
			print(plr.Name)
			
			
			plr:Kick(Reason)
			script.Parent.Callback:FireClient(returnPlr, "Successfully kicked "..plrName)
		else
			script.Parent.Callback:FireClient(returnPlr, "Invalid")
		end
	end)
	if not Success then
		
		script.Parent.Callback:FireClient(returnPlr, "Error | Devs Check Console")
		error(Error)
	end
end)
~~~~~~~~~~~~~~~~

What the event returns is the player's name and reason. These all return the correct things. But no matter what I do, I cannot kick another player. It kicks me for an unspecified reason.
I came with no errors, it returns the plrname and reason correctly. 
What am I doing wrong?

Thanks in advance

Your script is not safe from exploiters.

None of those answers answered. I forgot to read the docs! If firing from the client, when getting it from the server, it also returns the player who sent it
