can you post a screenshot of what your optimization dialog looks like at the end of the solution?
i can't tell if you're saying that the optimization mode is showing the wrong results or if it is showing solutions that aren't valid in the wrong color. it will show all solutions, just some will be marked as successful and some not depending on yoru criteria.
also, your case seems pretty simple. one thing i'd suggest is running the cases manually and looking at the results. that might help you understand what may be happening.
