Please help Identify what MSS54 DME version do I have in my E46 M3 (with P0207 code)

[y2k_o__o]

I am working on reflashing the DME to erase the Build Journal Tune back to stock tune for my 01/11 production date M3. The sticker on DME matches chassis, so I am sure this is the original DME from factory.

But the info in INPA and WinKFP seems contradicting to me.

Why does it shows MSS52 DS0 in INPA? (Rework program MSS52 DS0 for S54 ??????)

Many Thanks !
