Am I doing something wrong in this?
No, you're doing things right. I also noticed the same issue with the MIDI - unfortunately this is the nature of MIDI drum triggers, and these recordings often require cleanup - not just for velocity, but for mistriggered notes. As we only use the MIDI for notation, we don't really look at the velocity values when editing, as it would take substantially more time to do so.

Thankfully other RealDrums are more accurate in regard to velocity - it just happens that the one you chose is not.
