When online GUI.Label (or text area etc) shows overlapping text

You can see my small script below. It simply resets the players position when they fall below a certain height and adds one to their death count and also the team's death count.

 using UnityEngine;
 using System.Collections;
 
 public class Scoring : MonoBehaviour
 {
     public float lowestFallDistance = -10;
     private int deathCount;
     public static int teamDeathCount;
     private string deathCountString;
     public static string teamDeathCountString;
     private int screenWidth;
 
     void Start()
     {
         deathCount = 0;
         teamDeathCount = 0;
         deathCountString = deathCount.ToString();
         teamDeathCountString = teamDeathCount.ToString();
         screenWidth = Screen.width;
     }
 
     void Update()
     {
         if(this.transform.position.y < lowestFallDistance)
             Reset();
     }
 
     void OnGUI()
     {
         GUI.Label(new Rect(5, 5, 30, 20),deathCountString);
         GUI.Label(new Rect(screenWidth - 35, 5, 30, 20),teamDeathCountString);
     }
     
     void Reset(){
         this.transform.position = new Vector3(0,2,0);
         ++deathCount;
         networkView.RPC("PlusTeam", RPCMode.AllBuffered, "");
         deathCountString = deathCount.ToString();
     }
     
     [RPC]
     void PlusTeam(string empty) {
         ++teamDeathCount;
         teamDeathCountString = teamDeathCount.ToString();
     }
 }
 

The team's death count in the top right only shows once, and just as I intend it to, but the player's individual death count in the top left is always zero with the actual count displayed on top.

This only happens when I play online. If I play single player and die it just shows the correct score without a zero underneath. I really don't see what I've done wrong so any help would be greatly appreciated.
