3593025 - Data Workbench Update Issue: Main Indicator Changes Not Reflecting in UI for Account Contact Persons

After successfully updating the "Main Indicator" from "TRUE" to "FALSE" for Account Contact Persons via the Data Workbench (DWB), the changes do not reflect in the user interface (UI).
Despite the update being completed without errors in the Excel file, no changes appear in the system, and the UI still displays the old values. This indicates that the update process did not properly sync with the system's UI, leaving the data unchanged from the user's perspective.
