My balance in the game and my multiplier are not saving, i cant figure out why, any help?

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public static class SaveGameData
 {
 
 
     // Save the game automatically when the player quits
     public static void Save()
     {
         // Save the current system time as a string in the player prefs class
         PlayerPrefs.SetString("SaveDateTime", System.DateTime.Now.ToBinary().ToString());
 
         // Save total balance
         PlayerPrefs.SetFloat("Balance", GameManager.instance.balance);
 
         PlayerPrefs.SetFloat("allprofitmultiplier", GameManager.instance.allprofitmultiplier);
 
 
         // Save all stores settings
         SaveStores();
 
         // Save all upgrades
         SaveUpgrades();
 
         // Update the preference file so we know that game is saved.
         PlayerPrefs.SetInt("GameSaved", 1);
     }
 
     public static void SaveStores()
     {
         int counter = 1;
         foreach (Store storeObj in GameManager.storeList)
         {
             
             PlayerPrefs.SetFloat("storecount_" + counter, storeObj.storeCount);
             PlayerPrefs.SetInt("storemultiplier_" + counter, storeObj.storeMultiplier);
             PlayerPrefs.SetFloat("storecurrenttimer_" + counter, storeObj.CurrentTimer);
             PlayerPrefs.SetInt("storetimer_" + counter, storeObj.storeTimer);
             PlayerPrefs.SetFloat("storeprofitmultiplier_" + counter, storeObj.profitmultiplier);
             PlayerPrefs.SetFloat("basestoreprice_" + counter, storeObj.baseStorePrice);
             int Unlocked = 0;
             if (storeObj.hasManager)
             {
                 Unlocked = 1;
 
             }
 
             PlayerPrefs.SetInt("storemanagerunlocked_" + counter, Unlocked);
 
             Unlocked = 0;
             if (storeObj.storeUnlocked)
             {
                 Unlocked = 1;
             }
 
             PlayerPrefs.SetInt("storeunlocked_" + counter, Unlocked);
 
             counter++;
         }
     }
 
     public static void SaveUpgrades()
     {
 
         int counter = 1;
         foreach (Upgrades storeUpgrade in GameManager.storeUpgrades)
         {
             PlayerPrefs.SetInt("upgradecounter_" + counter, storeUpgrade.upgradeCounter);
             counter++;
         }
 
     }
 }

this is my savedata script, if the problem is not from here tell me so i can show my load game script maybe the problem is there, the only thing that doesnt get saved to my knowledge is balance and allprofitmultiplier.
