Well, facts about Madara's Rinnegan:
 * actually created from Izuna's eyes, not Madara's own
 * Izuna's eyes became Rinnegan after merger of Indra's chakra in Madara with Asura's chakra in Hashirama's cells that Madara had stolen
 * Madara is no longer Indra's incarnate after being revived

So why did Hashirama's face stay but not Izuna's eyes? Can't make sense of it either, sorry :D
