Just look at it again, I don't think this is a bug, one is from the pgn, and another one is from UI (I guess). If you don't like the duplicated you can delete the comment at the end of the game.

I think it is a bug in the process of adding a game to the study. It shows up in the PGN twice.

It seems to behave differently on mobile firefox than desktop firefox. Example study output https://lichess.org/study/xzvOGYmS/YmWPxotb chapter 1 is from mobile site, chapters 2 and 3 from desktop site

ah, there are two comments, I only saw one when I tried to reproduce. I also use firefox desktop.

Is this still happen today (or yesterday for that matter?)

[jxu]

Yes it's still happening on my desktop.
