Thank you for your question regarding the ‘auto-description’ that Facebook makes. It appears that Facebook builds this faux title from your Site Title, and the Page Title. You can change the Site Title from the Customizer section of BoldGrid. The Page Title can be changed from the ‘Pages‘ section of your BoldGrid dashboard. Also, please keep in mind that it appears that Facebook has its own internal cache that you may need to wait to update after you have made changes.
