Hi @Harry S,
Thanks for the video, super helpful. I can see a replication of what you're seeing. I agree it's probably not a bug, but it's definitely a desired feature. I don't have an answer for you now, but if you highlight the caption track along with the clip, you can trim them together. Or, depending on how much adjusting you've done to them, you can regenerate the captions after the trims are done.
