Note that changing an Enterprise name changes it everywhere in the application.
Navigate to Enterprise Settings for the Enterprise whose name you would like to edit.
Select the ‘Other Actions’ tab, which is the rightmost tab on the screen.
Click the pencil icon to the left of “Edit Enterprise’s Name”. The name as it appears in the list on the left side of your screen will be editable.
Click on the name and type or delete until the desired name is visible.
Press ENTER or RETURN on your keyboard to commit these changes. Click the red CANCEL text underneath the Enterprise name to revert back.
