Any clip, even template I add to the timeline unlink the audio from the video, but they don't show up as unlinked to link them back when you right click the clip or template. You can't link them back together, and options to synchronize or group are greyed out. If they are shifted out of sync, you can move them back into sync. Because of this issue, every time I cut a clip, I have to cut both the audio and the video separately. I've added screenshots for reference.
