When widgets that run on tick visibilities fail to display correctly in standalone, it is most commonly due to uncommunicated errors on compile.
Look for amiss nodes and things that are loading after the widget that the widget references. Failure to capture core functionality can force the widget to sit in an error state (where it is just showing and ignoring all input).
Remember that standalone lets less things slide, PIE (play in editor) will account for minor errors and warnings where standalone allows less and a full package even less.
