Can't move clips on timeline
I am working on a student project. The professor has given me an After Effects template to package my project.
My creative cloud app says that After Effects is up to date. (23.0.0 (Build 59)
I am on Mac OS-X 13.0.1, which is supposedly also up to date.
The template has an introductory clip and two ending clips, for credits and the college logo.
Then it has a clip (#2 out 4) where I can insert my work. The place where I am supposed to insert my work is originally set for 1 minute, but my work is 10 minutes. I have reset the composition settings both for the entire template and for my clip to accommodate the longer work. I have three clips inside my section. I have no trouble arranging those within the section and getting them to preview. I can slide them back and forth on the timeline.
The problem arises when I try to slide the credits and the closing logo to be after my work. They will not slide. They are most definitly NOT locked.
The professor has sent me a video where he shows that he can slide them on his PC. I have tried to follow his instructions. I have shift selected both clips. I have pressed shift and then drag. I have tried using the onboard trackpad and an external mouse. I have locked and unlocked the clips, just to make sure. They will not move.
I have read a number of online posts that say that when a clip will not slide that means it is locked, but the lock logo is most definitely not showing for these clips. As I said, I have turned it on and off.
I have created a youtube video of a screen capture, showing me trying to drag the final two clips https://youtu.be/Q3H1AFKS1mI
