Custom Time Attribute Stores Old Value while resubmitting the Timecard

Summary:

We have a requirement to manipulate the State(Seeded Field on the timecard)/ Province(Custom Time Attribute on the timecard) to Home Location if Remote Work Flag Attribute is marked as Yes on the Timecard. For this requirement, we have already developed a Fast Formula which works as expected in most of the cases but in a scenario where these fields are updated or corrected after the timecard is submitted once we see a second row holding the old values. These attributes are dependent on Payroll Time Type from the configuration. We have a custom time attribute 'AG_TL_CAN_PROVINCE' configured in the instance
