Auto-Reframe after cropping

I have 1 video shot from 1 camera of a discussion between 3 people. 16:9 aspect ratio.

I'm coverting the video into YouTube Shorts, TikToks, etc.

I'm copying the same video 3 times onto the timeline, cropping each video track so that each track represents 1 of the 3 people. This way, I can cut between them.

I'd like to apply Auto-Reframe, however, when I apply it after the crop, auto-reframe still focuses in on the person in the center, even though that person is cropped out of the video track.

What should I do?
