Supply 9.5.1 Theme - Variant pages problem -

I want to switch to the Supply 0.5.1 Theme. However, I have many listings with variants. I note that when I click on the “name” of the variant in the drop-down pm a product page, the correct image appears along with the correct price. But - when I click on an image in the variant group, the “name” and price do NOT change. How can I correct this? If a customer clicks on an image they like, they need to see the correct name AND correct price. Thank you.
