How to clone parts with random Orientation and Position without cloning multiple?

I am making a game where you pick up leaves that fall from trees and sell them for money. I made a script to Clone leaves with a random position (-15.5 to 15.5) with a random orientation, the orientation being in increments of 15:

function reroll()
    local leaf = script.Parent:Clone()
    leaf.Parent = game.Workspace.Leaves
    leaf.Position = Vector3.new(math.random(-15.5, 15.5), 1.75, math.random(-15.5, 15.5))
    leaf.Orientation.Y = (math.random(1, 12) * 15)
end

reroll()

The script clones these leaves into a folder in workspace called Leaves, as seen here

local leaf = script.Parent:Clone()
leaf.Parent = game.Workspace.Leaves

The problem is, when I put the "reroll" function at the end, it clones 3 in random positions instead of 1. It also clones a 4th, but that one remains with the same position and orientation as the reference leaf that I am cloning (the parent of the script). I want to clone just 1 leaf with correct orientation and position. Any help is appreciated. Thank you.
