Clear Links command missing


I’m not sure if this is a bug, but after creating a link between 2 documents in the References section I decided to remove the link. Section 8.2 of the user manual says that the way to do this is to select the link and right click on the selection, however, when I do so there is no CLEAR LINKS command. I could remove the link by deleting the link and text and retyping, but this is a bit cumbersome.
