Howdy Krystyn,
I would love to help you with this.
By default the entire description does show. You can see an example of the default here. However some themes opt to show the excerpt instead, or some don’t show anything at all. Sometimes this can be altered by going to WP-Admin > Events > Settings > Display and changing the Template, but sometimes it can’t.
You mentioned the homepage of your site, are you using a widget to display upcoming events? If so that widget is not designed to show the entire event details, just the highlights. You’d need to modify it to show more, which could be done with a theme override (Themer’s Guide ).
Id you need further help would you mind logging in so I can verify your support access? Or, if you don’t have/want a license (which includes a year of support) you should checkout the volunteer community on WordPress.org: The Events Calendar. It’s not the same level of support, but it’s free! We even check those forums once each week and help to the extent we can.
Cheers!
