Same applies to teleport trigger and time warp trigger too, but I replaced them all, so nonapplicable.
Usually when I use channels to dictate the direction and flow of the music line, it follows the same orientation as the arrow triggers. But instead of bouncing left and right like I thought it would, the music line would bounce left when in contact with the first trigger, but the instant it touches the next arrow trigger, it teleports.
I'll record a video to show it.
As of debugging, I'm not too sure on what I should even do. I never use this trigger.
