Shopify Template Issue: Fixed Position Problem with Specific Product

I'm stuck. I have created a product template that I want to assign with a certain product in Shopify. When I preview the template with that product, all the sections I add underneath the the product section get a "fixed position" property and display on top of screen. I have checked the properties of those sections and none of them have fixed property. What's even strange is when I preview the template with any other product and it works fine. In fact all the product templates I have created behave the same way with this particular product. I have tried reaching out to support but no luck.
