MIDI Merge, MIDI from insert on another track coming in?

I am a Cubase Artist 8.5 user and I am experiencing a to me strange phenomena.

Often I like to use MIDI Merge function to print the Arpache MIDI insert on on tracks. :nerd:

When I have a Stepdesigner MIDI insert on another track (I often use it as a SideChain trigger) the notes from the Stepdesinger get printed on the wrong track. Pretty annoying… :confused:

I have experienced this in multiple projects. I always solo the track that I want to print.

Am I doing something wrong or is this a bug :question:

Don’t know if this helps, but I sometimes forget to look at which track is highlighted. As you know, clipboard objects such as MIDI data will always paste to the highlighted track.
