Edit Subforms: Does not save data properly

I have a CUSTOMER form with a PROJECT subform.

When I go to my CUSTOMER View and Edit customer 123, I see 2 project rows. The first row should contain agreement 12 & the second row should contain agreement 22. After I change the agreement value and click update, I go to the view PROJECT rows but it did not save properly. However, the PROJECT agreement for 1 row is blank and the other is correct.

Before I submit Update: (Expected)

After I click Update: (actual)

Why is the data not saving properly?

The application is open for editing

Application: Services & Asset Tracking

Form: Customer
