MS Excel Auto Save not saving the workbook

When I use Excel Application Scope with Visible disable and Autosave enabled. The Workbook is not performing Autosave once the scope gets complete. Is this how its supposed to be?

If we have enabled auto save property in the property then the excel file which Is opened with excel application scope will get saved for sure
If we want we can still use
SAVE WORKBOOK activity inside the excel application scope as a last activity within it
For more info

Hope this would help you
