The Events Calendar plugin runtime error caused by Newspaper 9.6

Relevant page: https://personacentral.com/events/

Recently, when I hover over any event in the calendar, the pop-up windows permanently stay on the screen, and start to overlap each other. An example image: https://i.imgur.com/lJStx6Q.jpg

I’ve discovered that the problem goes away when the “Disqus for WordPress” plugin is disabled. But more importantly, when the theme is changed from Newspaper 9.6 to something else, and the Disqus plugin is still enabled, the problem goes away as well.

When I inspect the source page, numerous problems come up for each event pop up, and it looks like this:

Seeing the “tagdiv” parts of the error message and the fact that it goes away when the theme is changed, this makes me think it’s related to something with Newspaper. I don’t know why it goes away when the Disqus plugin is disabled, however.

Also to note, the problem might not occur if the page is directly accessed. But if you go to the home page, and then to the Events page, the problem will happen.
