On user-input Action for Subform Fields

On user-input Action for Subform Fields

I am having a strange issue where an On User-Input Action is not being executed when editing a subform fields after opening the Main form and attempting to edit a field in a row.  However if you add a new Row, then add data to the field, the On User-input Action is executed.  When you do the same action on a Row that was already in the record when it was opened for editing, the Action is not executed. I have screenshot but the system is not allowing me to upload them. 
 
The Application is ghsagjv/projects/ 
The form is Time_and_Expense_Submission
