No calendars loading correctly

I’ve installed the All-in-one WP plugin, added events, styled the theme colors and fonts and added it to my calendar using the shortcodes. When I view the page, the info is all there, but doesn’t display any of the correct calendars (posterboard, agenda, weekly, etc). It’s like it’s missing the style sheet – thought it IS loading all the correct colors.

See the problem here: https://b32.eb1.myftpupload.com/calendar

I don’t think that it is the theme (Divi 3) or plugin conflict because I’m using the same theme, plugins and shortcode for a different website and it works perfectly.

Thanks for any help.
