I'm working on editing an interview in which I have two videos and one audio and I have them all synced and I am trying to group them so I can easily and accurately cut parts out without worrying about messing up the sync but when I highlight them and click on group it won't allow me to create a new group. I ungrouped everything and now every option under the group button won't work and neither will the keyboard shortcuts. I've googled and found nothing on my problem.
