Scenario:
We checked the opportunity and found that after form submission, the field values were changing from “Completed” to null.
Root Cause:
The “Save form at each step” option was enabled, and the payment was configured in the second tab. As a result, the field value in the first tab was blank. After the final payment submission, the system received a success response, which caused the issue and reset the value to null.
