Hi Davon-
Thanks for reaching out, and thanks for using the Post and Page Builder for WordPress.
As far as I can tell from looking at it, that calendar should be there in the Edit Page editor you mentioned. The calendar itself is a Widget, and it looks like it’s been inserted using a Shortcode into the top of that page’s content.
If you don’t see it when you edit the page, one thing you can try is to switch over to the Text Editor tab and use the Ctrl-F shortcut (Cmd-F on a mac) to search for the text wp_calendar
. Once you find it, delete the entire shortcode including the brackets: [boldgrid_component type="wp-calendar"]
.
