system hangs

I have this plugin set up for a product: https://store.pacificdomes.com/product/dome-home/
When the page first loads, if the top radial inputs have none selected, then clicking on any of them causes no action. After a while, can click on any but the first. It’s hard to tell if it just requires a moment to load the code or if the first option item just doesn’t work unless one of the others is picked, too random to test. Also, while it is configured to ‘none selected’ in incognito mode, the first item is selected.

The page I need help with: [log in to see the link]
