Hide default Author bio box

Hi, I would prefer to utilize a plugin to display Author info in my blog posts (plugin: Ultimate Author Box Lite). I have enabled the plugin, but the default Author bio is still displaying. How can I hide the default bio? Here's a screenshot - https://snag.gy/iHYF6A.jpg The plugin bio is on top; the default bio is on the bottom. Here's the URL for the same page - https://ourladyofsorrowsschool.org/2017/12/6-tips-for-a-successful-transition-to-middle-school/ Please help. Thanks. FM
