Issue with starting/canceling invokes

Im having an issue with canceling/starting invokes in my update. I have a time "frenzyTimer" which sets a bool in another class in which will state what type of invoke should be running. The start invoke works fine. The first if statement in update works fine also. Its just the second if statement that doesnt work. The debugs are being called but the "FrenzySpawn" invoke is never cancelled and the "SpawnBall" invoke is never started. I even check to see if the invoke is not running, as isaid. The debugs are being called correctly. Help please. Thank you

 public GameObject defaultBall,lifeBall,pointsBall,frenzyBall;
 int invokeCount;
 int spawnLocation;
 float xPos;
 float frenzyTimer;

 int lifeBallChance;
 int pointsBallChance;
 int frenzyBallChance;


 private void Start()
 {
     InvokeRepeating("SpawnBall", 0, 6); //Run the SpawnBall method every 6 seconds
     invokeCount += 1; //Counts how many balls have been spawned
 }

 private void Update()
 {
     if (Ball.frenzyActive == true && !IsInvoking("FrenzySpawn")) //if frenzyActive is true and "FrenzySpawn" is not running
     {
         CancelInvoke("SpawnBall");
         InvokeRepeating("FrenzySpawn", 0, 1);
         Debug.Log("frenzy is active");
         
     }
     if (Ball.frenzyActive == false && !IsInvoking("SpawnBall")) //if frenzyActive is false and "SpawnBall" is not running
     {
         CancelInvoke("FrenzySpawn");
         frenzyTimer = 0;
         InvokeRepeating("SpawnBall", 0, 6);
