The pop-up featuring variable product properties is no longer functional

I’m facing the following situation:

For a project, I am using WooCommerce Product Table Lite. This worked well until the pop-ups where the customer can choose the type of variable product they prefer and confirm it. It doesn’t matter what variables you provide or if you leave them empty. In this case, an error message appears in a new window (thus leaving WooCommerce Product Table Lite), on the ‘single-product’ page. If you then click ‘add’ on the product itself, they are added to the cart afterward. However, they are no longer added in the pop-up.

In principle, there is no intention to refer to the single products; everything should ideally take place within WooCommerce Product Table Lite. Are there others experiencing this issue?

Thank you very much in advance for your assistance!
