Unicon Theme + WooCommerce Variation Drop-Down Menu Error

Hello,

I just noticed a recent bug using the Unicon theme alongside WooCommerce. I noticed it today and have not been able to find the source of the issue – even after deleting all my custom CSS and updating WooCommerce and the theme files. When I switch to another theme however, the issue disappears, and so after much testing I concluded that it is very likely a theme-related issue.

On the product page of our site, product variations (Choose an option) cannot be selected in the drop-down menu. I know that on the back-end it is working fine, because if you click on “add to cart”, the option selected, though invisible in the front end, is added to the cart and the checkout process occurs normally. So this seems to be a front-end issue mainly.

Here’s a product page example: https://cyberdefenses.com/product/nist-program-cui-wisp-diy-nist-800-171-compliance-course/
Here’s another example: https://cyberdefenses.com/product/iapp-dpo-training/
Screenshot of the issue: https://www.awesomescreenshot.com/image/2995681/3ecb21dd892a1362b54440a5d5995530

All products on the store that have variations have the same issue.

I appreciate your help in solving this. I’ve been at it for several hours and, well, here I am! You’re it 🙂

Thank you.
