This isn’t a feature of recorded shows, and the content I screenshotted isn’t from recorded shows either; it’s from regular TV show content. This option isn’t part of the library settings; it’s set at the show level, not library level. And it only works for TV libraries, not Movie libraries.
As far as I know, you can only set this option individually at the show level; you cannot set it for the entire library. And there is a suggestion for Universal auto delete, you can vote for it.
