WALS has data for a language Zhang-Zhung where the ISO code given is [jna]. However, I confused Zhang-Zhung with Jangshung; these are separate languages. Zhang-Zhung is an ancient language of Tibet and hence does not qualify for inclusion in WALS. The ISO code [jna] is for Jangshung but there is no available data for this language. What this means is that Zhang-Zhung should be removed from WALS and the links to it from the genus Bodic within the Sino-Tibetan family also removed.
