But I still wouldn't cut the branch off, leave it as it is, and hope for more. It looks pretty healthy to me except that one dead leaf. Just carefully cut that one off with a scissors, not a knife.
It looks like the leaves wrap around the stem, so you don't want to completely cut them off. They're meant to provide a protective covering for the stem - always think about "what happens to this plant in nature?" before you cut off anything. Out where these grow naturally, nobody cuts off the dead leaves, right? They eventually dry and drop or break off, but probably leave their 'wrapping' around the stem.
