Difficulty Integrating Eventbrite purchasing with Code Block

Site URL: https://www.wearecapcon.com/tickets-on-sale

I have integrated the code provided by Eventbrite into code block, which is meant to allow purchasing of tickets to be performed on my Squarespace website. Unfortunately, when visiting the page, the code block doesn't trigger and the ticket purchasing display doesn't appear. However, if the page is refreshed, the code block is triggered and the ticket purchasing display appears as it is meant to.

The issue appears to be with how the website loads, and when I visit the ticketing section of the website, it is transitioning rather than loading, therefore not triggering the code block.

Any advice, help or assistance is appreciated in getting this to work. Please use the site URL provided to see what I mean.
