I entered the cue as popovers, but in certain parts the lyrics’ height does not adjust. The panel only appears as shown in the picture. How can I fix this?

Even if I drag down the part marked in red, it returns to its original position.

I can’t reproduce that. Could you upload a cutdown file that shows the issue?
I can’t upload it due to security reasons.
I have reworked it.
