I didn't see anyone else report this, so...I'm in Mooshu, Khotan skyway, working quest This Is The Pits. The walking cherry trees don't have real names. The quest says to "defeat UnitNames_00000303" in both the quest log and the active quest at the bottom of the screen. The walking cherry trees themselves have no names hovering over them. In battle, they are all titled "Missing Name". The quest does appear to update properly when you defeat them. I've got screenshots if you need them.
