I must admit I was confused why 'Time and Again' appeared but then I found another article on it. Reading this article, they mention that Netflix disregarded the first two episodes of any of the series because they would be the most watched of all. Especially with people who'd never seen it before (I know - weird right?) Usually after two episodes they've decided whether to stick with it or give it a miss. I presume that Voyager's first-time viewers took a little longer to decide and watched 'Time and Again' as well. (Or they left the room and left Netflix playing...)
That would explain it
