I tested different scenerios e.g added more than one RUN lines with different value of -verify, what I concluded on is that if we have multiple  RUN lines with each of them having no directive, the prefixes generated is always of the first occurence  with no  expected directive so, the error is always generated for the first occurence with no expected directive.
