Standard Support Tab is not Showing on an Administrator Role

The user has an Administrator role and the NetSuite Support Center role is already added on the Employee record. However, the user still can't see the standard Support tab.
 
1. Navigate to Customization > Centers and Tabs > Center Tabs.
2. Click Edit on a custom tab assigned with a Classic Center type.
Note: If there are several tabs with Classic Center type, look for the custom tab that contains the categories inside the standard Support tab:
- Help
- Communities
- Directories
- Customer Service
- Feedback
3. Change the name of the tab back to the standard name which is Support.
4. Click Save.
