Where does it do that? I've never come across such a phenomena (although Aberdeen used to have a nasty "hole" at the end of the ILS, IIRC).
Try a fully coupled approach (SPZ7000 or similar) and you should find the RoD remains fairly constant all the way to a 60ft height hold, commensurate with IAS, of course. I suspect Elan Head has it right: past DH, look up and continue visual and you will often gently climb above the indicated GS once all the visual cues take you further down the runway than the ILS aiming point
