UltimateArceus3 - In this situation you need the local storage to make you a backup of the value of the variable so that when you load a saved data, your variable can be updated by the backup from the local storage since local storage's aren't affected by saved data's.
Example;
You have a variable named "Health"
And a local storage key named "Health_Backup"
*System->On Load Complete
----->Get item --> Key "Health_Backup"
*LocalStorage->On Item Get->Key "Health_Backup"
------> System->Set Global Variable Value-->Variable 1 to LocalStorage.ItemValue
------"That Should do it"------
