It may be that certain users or teams do not require access or edit abilities to item types which are irrelevant to them or have access/edit ability for business reasons.

No Access Rights

When a user’s team does not have access to a particular item type, all icons and menus to that item type will “disappear” from the Gold-Vision user interface.

Access Rights

If a Team has Access to an item, they will be able to View the information, but not edit or delete the item.

Edit/Delete Rights

The Edit option grants the team the ability to view the item and change it, but not to delete. Delete gives the team full control over the items.
