Emerald Hippogryph macro

[Dralie]

I tried adding the Emerald Hippogryph to my cast random mount macro, but it didnt work. I decided to make a different macro to just cast the Emerald Hippogryph, and it seems to want to use the item for the mount and not the spell, does anyone know how to fix this?

Edit: If I delete the mount item from my bags and log out and back in, the item is back in my bag.
