Steps to reproduce the bug
Go to white's move 21. Play 21... Bc2 22. Kc4 c5 23. Kc4 Rd4. Then, go back to 22... c5 in that line. Play 23. Ka5 b6. Use the arrow keys to go back to 23. Kc4. It only takes 1 use of the arrow key for some reason. Use the arrow keys to go forward twice.
What did you expect to happen?
After the right arrow key is used to go to 23... Rd4, hitting the right arrow key doesn't do anything as that's the end of that line.
What happened instead?
It goes to the other line.

Sorry, the steps to reproduce should say that you should play 22. Kb4, not 22. Kc4. Also, I found that if you start from 21. Kb3 and play 21... Bc4 22. Kc4 b6, then go back 1 play and play 22... b5, it incorrectly lists the last move with "21...b5" and doesn't show the actual moves 21... Bc4 or 22. Kc4.
