Revert to a Personal Grid Definition
If a system administrator adds or removes a column in the original Grid definition, the new Grid definition is automatically pushed out to every instance of the Grid, thus overriding your personal Grid. You must then choose to use the new System Grid Definition or revert to your Personal Grid Definition.
This option is available only the first time you view the Grid (after logging in or reloading your definitions) after the system administrator has made changes.
To revert to a personal Grid definition, right-click the Grid header, and then select Revert to personal settings.
