Sequences - Playing Outside the Defined Bounds when Placed (Picture in Picture)

Hello all,

Probably a silly question (and likely confusing as heck), but I'm at a loss and hope you could help.

On a current project, I am attempting to create sequences of stills and video footage, adding panning and zoom with an intent to bring them into my main video as a quarter screen picture-in-picture (like, a news broadcast with the little image/footage placeholder above the left or right shoulder of the anchorperson).

However, after the first few worked great, I now have an issue where all the new sequences I create are playing outside the their defined bounds. What I mean is, when I bring the sequence into the main video, the first few I made remain within the static bounds of the sequence size chosen (such as 16:9 or 3:2). The panning and zooming all working in a perfect Ken Burnsy style, like as I want.

However the last few I made are not working. Instead of staying in the 16:9, 3:2, 4:3, etc bounds... once they are placed in the main and played, they will float and dance around the entire screen, emulating the panning and zoom I created in the sequence, but without the edge boundaries that were supposed to be in place.

I very much hope this makes sense and sure I just have something unchecked.

Any help appreciated.
