What am I doing wrong?

For several seconds one of the cells that incorrectly turned, begins to rapidly flash. Still a few wrong cells highlighted in red.

The error I showed on a light green background (you can't see them so easy) and in the top left to dark green.

Changed the animation hints at a much more visible. Now I do not miss.

Well, the fact of the matter is that I one cell prompted the saw upside down and nothing seems to be more highlighted.
thanks anyway for the help
