Recorded MIDI won't Merge

I have set up de MIDI Record Mode as “Merge” and MIDI Cycle Record Mode as “Mixed”. But when I record MIDI on an existing part in de Project Window, it still creates a New part on top of the existing part. To merge those two parts into one, I have to manually use the Merge-tool.

What am I doing wrong?

Hi,

Where is the Cursor, when you start (the second) record? Is it before-, in the range of-, or behind the already existing MIDI Part?
