MenuItem checkboxes disappearing on compile

Whenever my scripts get compiled (any time I make any changes) all of my custom menu items with checks get turned off. I tried updating them in a static constructor, but that never gets called. How can I get them to remain as they are?

 public const string clientMenu = "Build/Client";
 public const string serverMenu = "Build/Server";
 
 static BuildEditor()
 {
     EditorApplication.delayCall += Update;
 }
 static void Update()
 {
     foreach (BuildTargetGroup buildTarget in System.Enum.GetValues(typeof(BuildTargetGroup)))
     {
         if (buildTarget == 0 || buildTarget == (BuildTargetGroup)5 || buildTarget == (BuildTargetGroup)6 || buildTarget == (BuildTargetGroup)15 || buildTarget == (BuildTargetGroup)16)
         {
             continue;
         }
         if (PlayerSettings.GetScriptingDefineSymbolsForGroup(buildTarget).Contains("SERVER"))
         {
             Debug.Log("is server");
             Menu.SetChecked(serverMenu, true);
             Menu.SetChecked(clientMenu, false);
             break;
         }
         else
         {
             Debug.Log("is client");
             Menu.SetChecked(serverMenu, false);
             Menu.SetChecked(clientMenu, true);
             break;
         }
     }
 }
 
 [MenuItem(serverMenu)]
 public static void ChangeToServer()
 {
     if (Menu.GetChecked(serverMenu))
     {
         return;
     }
     Menu.SetChecked(serverMenu, true);
     Menu.SetChecked(clientMenu, false);
     foreach (BuildTargetGroup buildTarget in System.Enum.GetValues(typeof(BuildTargetGroup)))
     {
         if (buildTarget == 0 || buildTarget == (BuildTargetGroup)5 || buildTarget == (BuildTargetGroup)6 || buildTarget == (BuildTargetGroup)15 || buildTarget == (BuildTargetGroup)16)
         {
             continue;
         }
         PlayerSettings.SetScriptingDefineSymbolsForGroup(buildTarget, PlayerSettings.GetScriptingDefineSymbolsForGroup(buildTarget).Replace("SERVER", string.Empty) + ";SERVER");
     }
 }
 
 [MenuItem(clientMenu)]
 public static void ChangeToClient()
 {
     if (Menu.GetChecked(clientMenu))
     {
         return;
     }
     Menu.SetChecked(serverMenu, false);
     Menu.SetChecked(clientMenu, true);
     foreach (BuildTargetGroup buildTarget in System.Enum.GetValues(typeof(BuildTargetGroup)))
     {
         if (buildTarget == 0 || buildTarget == (BuildTargetGroup)5 || buildTarget == (BuildTargetGroup)6 || buildTarget == (BuildTargetGroup)15 || buildTarget == (BuildTargetGroup)16)
         {
             continue;
         }
         PlayerSettings.SetScriptingDefineSymbolsForGroup(buildTarget, PlayerSettings.GetScriptingDefineSymbolsForGroup(buildTarget).Replace("SERVER", string.Empty));
     }
