How to fix invisible variant buttons on product page?

I’ve activated a new product page using the Shopify Broadcast template. With three variants set by color, I’m having problems with the variant options not displaying properly when viewing the page. The names of the colors activate when I hover over them, but the circle variant indicator is invisible, making it look like the color variants aren’t there. I don’t see any variant color assignment options anywhere on the product setup page or variant option page.

Thanks in advance for any assistance!

Sample of where the variants aren’t showing properly.

Please follow the steps:
