Comments not displaying on Variable Products

Hello,

My site is no longer displaying the comment section for variable products, but it does display for simple products.

Variable:
https://bedroomsandmore.com/product/night-and-day-rosemary/

Simple:
https://bedroomsandmore.com/product/full-bedderbase/

If I have the lazy loading option enabled, I do get a javascript error on the variable product page. ” Uncaught TypeError: Cannot read property ‘scrollHeight’ of null “
