Formatting lost in Page Builder

I created an event using JCalPro and when displayed on the page builder it loses it's formatting. https://www.stjosephsprayercentre.com/ find it here: https://prnt.sc/26tqq6c
If you click on the event itself the formatting is fine.
Also, the row below is made up of the article scroller and this also loses its formatting. There is also a strange icon which appears next to the heading. Click on the indivdual article and the formatting is also kept. https://www.stjosephsprayercentre.com/retreats/events/93-the-meeting-of-a-disciple
Any solutions would be good.
