Unable to Use Buttons Like “Additional Information” tab on PDP

I am having an issue when customers visit my site, or when i visit my site on another browser (this issue does not happen when I am logged into my account)

The issue is that the tab on my product page does not allow you to view “Additional information” and also on my other pages like my FAQ “https://www.pro-storagesolutions.com/laundry-carts-material-handling-rotomolding-faq/”

On the FAQ – the drop down buttons do not work. BUT they work when I am logged into admin using site.

My assumption is there are other things being affected, but I am unsure how to troubleshoot.
