Weird Bug(s) in game analysis

I don't know if this is even the right way to submit a bug report, but there's something wrong with game analysis.
I just analyzed a game I finished recently and on one move the Trainer said I was threatening to win a rook. I didn't see how, so I clicked on "Show follow-up", long story short: The  follow-up started by white skipping a move (move 19.) and later basically sacrificing the rook for 2 pawns.

I've observed for a long time, that the comments of the trainers didn't always make much sense, and I also suspected that the suggested follow-ups where not in every case the best possible moves from both players, but this is the first time I saw a suggested move order that was not only bad but downright impossible.

Btw, Here's also a link to the game: https://www.chess.com/analysis/game/daily/785680169
