After Effects Template Layer "Locked" or disabled to edit

Hi everyone.

I purchased a Product Promo from Themeforest. Phone 6 3D Presentation by nikcina | VideoHive . It has been unzipped so I can save my changes.

While the screens can be replaced, I only need the first 10-11 seconds of the video, up to “Placeholder 5”, or even “Placeholder 2”, and want to extend that part to 90 seconds as I am placing a video tutorial in that space.

My issue is that the “final” layer seems to be locked as I can’t see the extra layers or how to edit or delete the remaining animations.

How do I go about editing it?

click the blue “hidden” dude

Oh wow… I am such a tonsil. :joy:

Thank you johnnybd
