I see no such inconsistencies, but I can see why you think that.
In a sense it hasn't. Baha'u'llah was a Manifestation of God whose Divine mission was disclosed to Him while in prison in 1852. He passed away 1892 but left a will authorising Abdu'l-Baha to be the leader of the Baha'i Faith, authorised interpreter and expounder of His teachings, and the perfect exemplar of Baha'i teachings. Abdu'l-Baha passed away in 1921 and left a will authorising twin successors. First their was the appointment of his eldest grandson, Shoghi Effendi to be the leader of the Baha'i faith and authorised interpreter. Shoghi Effendi passed away in 1957. Second, Abdu'l-Baha also appointed the Universal House of Justice that would be the head of the Baha'i Faith and established in 1963. We see that this international elected body can be the recipient of Divine guidance, but not to provide a revelation like Baha'u'llah as they are under the shadow of is revelation. Our international governing body is authorised to resolve difficult matters that pertain to the Baha'i writings, and can enact laws and repeal those same laws depending on the exigencies of the time. They provide ongoing guidance to the international Baha'i community that is Divinely inspired.
