No Data Displayed After Refreshing Extract

Follow the steps below to ensure to refresh the data without having to recreate the metadata (Groups, Calculated fields, Folders etc).

1. Connect to the published workbook from Tableau Desktop by clicking Server > Open Workbook.
2. Create a local copy of one of the affected published extracts.
3. Remove the extract filters or data source filters, if any.
4. Recreate the extract from the live connection.
5. Verify the data pane contains the desired metadata including the new values (Groups, Calculated fields, etc).
6. Publish the extract under the same published data source (overwrite).
7. Repeat steps 2 to 6 until all data sources are up to date. 
8. Quit Tableau Desktop without saving the workbook.
9. Verify the published workbook (unmodified) is showing the new values on Tableau Server Web-UI.
