Yes, that helps, thank you!
Inside the script those parts should be common text, so it should allow you to skip it if you've been through it already.
Occasionally I go over older parts in the story and make small adjustments, rewording things, updating sprites, or changing transforms. I'm not sure if this is the case, but I'm guessing that might mess up what ren'py considers seen or unseen text in some situations.
I'll look into it.
