Gift Card not switching between variants

I have created a new Gift card and have added a few variants- $100, $250, $500, and $1000.
The variants show up on the product page, and the $100 works. But when I select any of the other variants, the value still stays at $100. When added to the cart, it is still $100 even if the $500 was the one selected.

the page itself is still a work in progress, but I have it set to active right now- so I can get this issue resolved. here: https://www.peachtreeaudio.com/collections/accessories/products/peachtree-audio-gift-card

If someone is able to assist, that would be amazing!

make sure that the variants are correctly set up in your Shopify admin, and check that each variant has a unique ID. It looks like the $500 and $1000 variants may not be correctly linked to the variant options or if you’ve customized the page or used custom scripts, there might be a JavaScript issue preventing the variant from updating properly. Double-check the code that handles the variant selection and the add-to-cart functionality and try adding a new test gift card with just a few variants to see if the issue persists
