Remove Author Bio from Pages

I cannot seem to locate where the option is to disable Author Bio's from Pages. Site: https://salesbrainwork.com/ Page is About Page: https://salesbrainwork.com/about/ It seems to only happen when I change the page layout from 'default' to something else. See that the About page is 'no sidebar' and the Contact page is 'default'. The Contact page appears as it should with no Author Bio. However, the About page shows an unwanted Author Bio because the layout was changed.
