you might want to try adding the 'unsafe' predicate to the delete edge command. I have seen somewhat similar behaviour (though i don't recall the exact error message) when i tried to delete the vertex directly by giving the @rid (delete #14:0) instead of using the delete vertex command. using the delete vertex command deletes any connected edges but if the record is deleted using delete @rid unsafe, it leaves the edges hanging around. after that, the only way to get rid of the hanging edge (no pun intended) is to use delete @rid unsafe on the edge in general, always use the delete vertex or delete edge commands and avoid using unsafe keyword.
