  Solution:
  
  Verify Changes: Before saving, ensure that you have made actual changes to the TOU formula. This could involve modifying parameters, adding new conditions, or changing existing values.
  Recheck Input: If you believe you have made changes, double-check the fields to ensure that they are indeed different from the previous values.
