Hi there,
Which standards are you checking?
The WPThemeReview one is spitting out false positives, as they changed the comment they read to make sure things are escaped properly from the last version of the plugin. See this comment for more info: https://github.com/WPTRT/theme-sniffer/issues/140#issuecomment-471263051
While the tool is helpful for checking if your theme is coded nicely or not, all the checks are automated, so it’s not perfect 🙂
