Hi Anthony!
I’m sorry to hear you’re having this issue, I know how frustrating it is to debug CSS, etc!
You’ve done a great job at isolating the issue, thank you! I haven’t heard of anyone else having this problem but that doesn’t mean it’s not out there.
It is interesting to note that the error is only on events generated with a shortcode. It would be helpful to see that in action on your site, can you create an unlinked page for me to view? That may get us what we need to fix it for you!
Let me know!
Cheers,
Trisha
