see AFAT genre
The context menu is working as designed to show the information in the resource. Each lemma has its own tagging for Genre and Source (and מסע also has a Semantic Domain reference). In this case, they happen to be the same, so it appears to be duplicate information.
I don't know if there are any cases where this tagging differs by lemma. If that never happens, then one could argue that the context menu should be special-cased to collapse that information into one row for just this resource, with appropriate design in the UI to indicate that it does apply to both lemmas and not just one.
