When Part 1 is triggered and running, Part 2 has green background (like it is active), and can’t be triggered. When Part 1 has an endless loop you’ll never get to Part 2. See video

When you want to trigger a part via the play button on the parts list while the song is running, the previous loop keeps running and you can’t select the next part. Also, you need to double-click on the play button. It works when you click on the part name instead of the button.
Both happens at least on Mac.
