Transparent png with multiply not working on blurred layer

HI I am learning webflow…
While I was able to get a transparent png on a background, when i blurred a div and tried to add a transparent png to it, it wasnt transparent anymore. In the link below if you scroll all the way down. You could see the same image applied but looking different depending whether it was on the blurred background or not.
Would anyone know of any work arounds?
