When you say "removed the bump" do you mean literally ?
I opened the original Royal Pointed Roof and compared them
The original on the right, yours has to look like that but blank ie the canvas has to be blank so to speak, you cant just delete it, you have to paint it the same grey all over as it is, and the alpha, effectively painting over it and wiping it clean, it should look the original in the right hand pic, but all grey. You have done the same with the spec too, it has to be black on both layers.
