Good evening Andrew and welcome to the Events Calendar Support forum!
Thank you for reaching out to us.
I would love to help you with this topic.
The short answer to your question, Avada actually includes a template customization for our plugins.
This is why the layout is slightly different.
The good news is that you should have total control over that customization. You might want to read our Themer’s guide to get a sense of how that works.
Basically, by using an Avada Child Theme and using your own /tribe-events/ folder you should be able to tweak things to your liking.
I would be glad to help with that of course should you need me to.
Let me know how that goes.
Best regards,
Geoff B.
