Correct its intentional as how could it target "two" different Things?
I need more info cause I can't find a "Favored Deity Weapon" ability and not sure I am following how/why the feat would be getting multiple tags?
Sorry. I mistyped the name of the feat. It's actually Favored Weapon Focus. It gets added to the character when they take the Cleric Domain "War".
In this case, the reason there are multiple Target tags is because some Deities have more than one favored weapon. An example is Hextor who has both the Flail and the Heavy Flail. Hextor is a deity from Greyhawk Gazeteer.
