Why is it not showing my gun's damage?

I have 3 guns here. The luger is a free model, and the Berretta and AR are both edited guns from a kit.

All of these guns are actually doing damage but it only displays how much health has been lost when the luger shoots, and not any other gun.

Here is a video showing the issue:

Damage Code for My Guns

	local baseDamage = getBaseDamage(Dist)
	if Humanoid.Health ~= 0 then
		local hitHumanoid = nil
		if H.Parent:IsA("Hat") then
			table.insert(customIgnore, H)
			local newRay = Ray.new(P - D * 0.1, D * (S.bulletSettings.Range - Dist + 0.1))
			local newH, newP, newN = workspace:FindPartOnRayWithIgnoreList(newRay, customIgnore)
