Quick question re: your QC and PD setup

Could someone do me a favour and let me know how many instances of QC and PD you see in your device setup / midi page. I seem to have 3 instances of these, with various combinations of active, visible etc

Therefore I get more than one appear in the channel strip drop-down box when assigning a midi in connection.

Is that by design or is my install wrong?

Would be really grateful for your input…
