charmbeautify WordPress Generated placeholders are not theme-specific. They work within WordPress to attempt to identify ad insertion locations based on the markup of the page after the theme has been processed. If we were to delete and regenerate the placeholders, they would be placed in the exact same location. Which then would cause a drop in revenue cause they would lose their performance information.
So as suggested by my team, if you are unhappy with the generated placeholders, you will need to make changes to these placeholders. If they are causing issues, we would be happy to take a further look but you would need to reenable the palceholders. Thanks!
