RE: method=ITS, OPTIMIZATION NOT TESTED (?!)

Hello NONMEM Team, I found method=imp useful when there are local maxima. Nevertheless, at the end of optimization it prints a message, which makes me feel somewhat uncomfortable: OPTIMIZATION NOT TESTED. Also, the final objective function is not always the lowest one. An example is below. How do we interpret the results in this case?
