Using the Class Connector to update an existing class that has a VLS setup makes the VLS settings to be deleted after the connector finishes the update.
SAP SuccessFactors Learning
Product Management and Development teams confirmed the connector is behaving as per design. When the new segment data is entered, the connector deletes the previously segment data and creates a new one, wiping the VLS informaton from the previous segment.
