Whats wrong with this app?

I downloaded this app about 3 weeks ago, and tonight was the second time when I solved the puzzle, got the message there were still one or two errors, I reviewed the puzzle for 5-10 minutes, couldnt find anything so revealed the puzzle to find . . . I had actually solved it correctly. Frustrating and broke a streak. Please fix.
