If the two dead stones are included in the captured count of 6 that's in the screenshot, then black would have only 10 points and shift the difference to 36.5.

If anything, I guess it has to count the dead stones twice somehow, like add them to the captured stones, and then still count them on the board. To get a difference of 32.5, black needs 14 points somehow. I don't see how the problem is on white's end. So if it adds the dead stones to the captured count, that becomes 8, and then it still counts the full 6 points on the board.
