You can restore entity views and property page grids to the default configuration.
Click Reset Layout to Defaults located in the lower left-hand corner of the Grid Customization page. This impacts all aspects of the grid configuration including selected columns, display order, sort order/direction, column widths. It also resets frozen fields, selection totals (if applicable) and any other grid customization option provided on the page.
Note: Selecting this option does not immediately save the configuration so you can make additional changes to the configuration after clicking Reset Layout to Defaults.
Click Save to update the configuration permanently.
Alternatively, click Cancel to close the page without saving.
