Apple released iTunes revision 12.6 at the end of last week. The new version eliminates hidden options that may have been accidentally integrated into the software. Shortly after the original release of iTunes 12.6 (Tuesday), a Reddit user discovered a "Show on Profile Page" option on the playlist editing page. But since there is no such profile page, switching did nothing. Now this broken option has been removed from iTunes 12.6, suggesting that it may have been added by mistake and we will see it in the future.
