Good evening Glen and welcome to the Events Calendar Support forum!
Thank you for reaching out to us.
We are sorry to hear about the layout not being up to par on your website while using the shortcodes. Yikes!
I would love to help you with this topic.
Could you please send me a copy of the latest version of your WordPress theme / child theme via a link to a .zip file link (stored Dropbox or Google Drive) so that I can run some tests on my end ? I recommend a private reply for that purpose.
Please ensure you are using the latest files as found on your actual website.
This way I will get access to any updates or customizations you might have made.
In the meantime, I would recommend trying different settings for the first 2 options found underĀ Events -> Settings -> Display to see if that helps.
Hang in there!
Geoff B.
