Google Search issues

Hi I am not sure if this is something you can assist on, however if you can, any advice would be appreciated. Theme: Catch Flames Pro v3.5 Site: http://energyfaculty.com Issues: 1. On google search engine, google display dates for static pages, we would certainly like the snippets to be displayed without dates for static pages. 2. Google Search Console/Google Webmaster Tools reports that 82 out of 85 pages contain Structured Data Errors ( missing "Updated" x 4 on each page, missing "author" x 4 on each page). We would very much like to avoid these errors. Please also be noted that when running the "online test" for the pages with reported errors everything appears to be ok....?) Kind regards Lars
