Hi wss310,
Try this shortcode and see if it fixes your issue.
[add_eventon_list number_of_months="10" show_upcoming="1" hide_empty_months="yes" ]
Are you using multiple shortcodes down the page or just what you have previously pasted in last message?
You may want to show the 'add_eventon_list' value to achieve what you are looking for. This will hide the empty months.
To achieve this, make sure to use the "Events List" from the shortcode Generator.
Let me know if this helps, if it isn't functioning the way you want still, please reply and let me know.
Regards,
Mike
