Hi, Erik.
I tested with X Theme version 4.6.4 and Cornerstone version 1.3.3 and my /events page looks just fine: https://cl.ly/1v1t1D0i1M0A
It might be an issue with the child theme you’re using (if any) or your X Theme settings (e.g. specific skin) or other plugins you’re using.
We cannot provide help for non-default WordPress themes (like Twenty Seventeen), per our Scope of Support / Terms.
Thank you very much for your understanding.
If you need some coding help, you may want to ask your theme author, site developer, or reference our documentation and list of known customizers.
