Hey Patti,
Unfortunately we are unable to offer support here in our pre-sales forum. However, to help you get pointed in the right direction, you can continue to use the month view only category that you’ve got set up and then follow our Themer’s Guide to copy the single-event.php file for the list view and add a conditional to not display if the event is in the selected category.
I’ll close this thread for now, hopefully this will help to get you pointed in the right direction. If you would like further help for the free plugin you can try reaching out on our forums on WordPress.org.
Thanks!
