Simply put, you can't. Due to the way WordPress works, you can't remove anything a theme or plugin adds to a post by another plugin.
What you can do, is one of the following:
Edit the theme or plugin that posts the incorrect data to remove the incorrect data, and then use this plugin to post the correct data (make sure to use child themes, or redo the changes after a theme or plugin update if you use this).
Also, some plugins can automatically edit your theme to remove SEO tags placed by your theme (WordPress SEO By Yoast, for example). This is a function I WON'T add to this plugin, because the goal of this plugin is to stay simple and multifunctional. This is not primarily an SEO plugin. Also, theme edits will be undone when the theme is updated, so this can require additional maintenance.
