They are both Kais making a full Kai still where as Fusion Zamasu was Half Kai and Half Saiyan, so Kibito can be in both but Zamasu F should only be in Fusion, and like Zamasu shouldn't go in the Saiyan category for being half saiyan body.

So Kai disambig is for pure kais.

Elder kai fusion retconned too.
