Hi,
Sorry for the issues you are having.
I can help troubleshoot this with you to get it resolved.
So I visited the site and see that when I choose the Music Category all the Events Shows.
However, when I visit the link the events are not showing, they are showing in the source code. So they are there, just hidden.
It looks like something is preventing the script from finishing.
Can you please try our testing for conflicts guide and see if that narrows down the issue.

Let me know what you find out and we can go from there.
Thanks
