Mindbody Enrollments Widget 'Next' and 'Previous' buttons not working

Site PW: YFTH

In Mindbody/Branded Web I created a widget and deployed it to my site. When I click the 'Next' and 'Previous' buttons it loads a new URL which results in "We couldn't find the page you were looking for." I've tested the widget by placing it onto a wordpress site that I have access to and the next and previous buttons work as indented—populating inside the widget itself without changing the URL. 

This is the code for the widget that was generated by Mindbody/Branded Web and inserted into the page.

<script src="https://widgets.mindbodyonline.com/javascripts/healcode.js" type="text/javascript"></script>
<healcode-widget data-type="enrollments" data-widget-partner="object" data-widget-id="0494389dacc" data-widget-version="0" ></healcode-widget>

The code was inserted into this page: https://raspberry-tetra-npmp.squarespace.com/workshops-events

It's working on another browser in incognito mode so I suppose I'll chalk it up to a SS editor/caching issue. Thanks for your help!
