Alchemist returning weapon

Cant select boomerang 

it’s a simple weapon 

It’s a ranged weapon 

And I know your going to say “the boomerang already comes back”, but not if you hit with it. Boomerang should be an option it meets all criteria 

Returning Weapon

Item: A simple or martial weapon with the thrown property

This magic weapon grants a +1 bonus to attack and damage rolls made with it, and it returns to the wielder’s hand immediately after it is used to make a ranged attack.

Boomerangs do not actually have the thrown property:

Type: Simple Ranged Weapon Cost: -- Weight: --

 

The boomerang is a ranged weapon, and any creature proficient with the javelin is also proficient with this weapon.

On a miss, a boomerang returns to the thrower's hand.
