Is roblox IntersectOperation bugged?

Hello all! I am working on a system using IntersectOperation. This is how i can best describe my problem:

Using intersectAsync function via code does not produce same result as using the intersect button in studio.

Here is the code that i am using to put decals on my intersectOperation:

local function GetIntersection(hit,ray)
	local newhit = hit:Clone()
	newhit.Transparency = 0
	newhit.Color = Color3.new(1,0,0)
	local Intersection = newhit:IntersectAsync({ray})

	return Intersection
end

module.PrintRay = function(ray)  -- raycast
		local hit = Instance.new("Part")
		hit.Name = "Sec"

		hit.Anchored = true
		hit.CanCollide = false
		hit.CanQuery = false
		local height = 0.25
		local width = 0.25
		hit.Size = Vector3.new(width,height,0.25)
		hit.CFrame = CFrame.lookAt(ray.Position, ray.Position + ray.Normal) -- * CFrame.new(0,0 (hit.Size.Z * 2))
		local cf = hit.Orientation
		hit.Transparency = 0
		hit.Parent = workspace

		local Part = ray.Instance

		local newhit = GetIntersection(hit, Part)
		newhit.Parent = workspace
		
		-- Sometimes its on the backside, idk why
		local bulletdecal = Instance.new("Texture")
		bulletdecal.Parent = newhit
		bulletdecal.Texture = "rbxassetid://" .. BulletDecalID
		bulletdecal.OffsetStudsU = width/2
		bulletdecal.OffsetStudsV = height/2
		bulletdecal.StudsPerTileU = width
		bulletdecal.StudsPerTileV = height
		bulletdecal.Face = "Front"

		local bulletdecal2 = Instance.new("Texture")
		bulletdecal2.Parent = newhit
		bulletdecal2.Texture = "rbxassetid://" .. BulletDecalID
		bulletdecal2.OffsetStudsU = width/2
		bulletdecal2.OffsetStudsV = height/2
		bulletdecal2.StudsPerTileU = width
		bulletdecal2.StudsPerTileV = height
		bulletdecal2.Face = "Back"
		
		newhit.CanCollide = false
		newhit.CanQuery = false
	end

This is what happens when it is executed:

NOTE:
The mouse in the video is duplicating the wedge and then selecting the square, and intersecting it with the wedge. The order of selecting parts matter

The red ones are the one done via code. The ray.Instance is a wedge, but it has similar problems with blocks and really all types of things. Sometimes the decal is printed on the opposite face, so i added 2 different decals.

Observations:
It helps if you via code face the square the same direction as the part you are intersecting with, didnt work if the part was on an angle other than 90.

Flipping the IntersectAsync makes things worse.

Is this a roblox bug? The video and excessive testing has resulted that if you do the intersections via roblox (not by code) it works perfectly. If you need more context it will be given. The code block is a simplified version of the actual code
