Hey Kevin,
Well done on running through all the steps I typically provide in these instances! I’d also like to point out that our plugins aren’t necessarily “bundled” with the Avada theme, rather the Avada authors chose to incorporate styling for users running both TEC/PRO and Avada.
I took a look at the link provided and experienced what you described. I’m not exactly sure as to why this issue is occurring. I was actually able to test and reproduce the issue on my local environment using the Avada theme, but these types of conflicts are unfortunately outside what we’re able to cover.
You might try contacting the Avada support team to see if they have any ideas as to why the shortcode output is disappearing. I wish I had a better answer for you but as previously mentioned, we’re limited in these instances. Thanks for understanding and enjoy your weekend.
Cheers!
