New heatsinks not touching chip surface and fall of again.

I executed the heatsink modification according instructions. The 2 old ones were both lying on the bottom. Then I glued the new ones on top of the chips and pressed gently. Done? I started to close the case but suddenly one of the heatsinks fell of again! After closely investigating I noticed that some surrounding SMD parts are (L2, L3, C11) higher then the surface of the chip! In other words it is not possible to mount the heatsink in such a way that it touches the chip. The only solution is to cut the new heatsink to fit the chip. Do I have different pc boards or why did not anybody else has this problem? What I‘m doing wrong? Chris DJ2NL

The pictures on the included instruction sheet show the proper placement of the heat sinks on the back of the Circuit board.
