I am supposed to launch my site tomorrow, but yesterday an error/glitch appeared seemingly out of nowhere. I sell posters, and the only variant option I have is for the poster size. There should only be one drop-down menu for this. For some of my products (not all), it now shows duplicate drop-down menus. Mostly 2, but some even have 3. Again, this happened out of nowhere and I have not touched any code. And it only applies to some products, not all.
I am using a 3rd party POD app so I don't know if the problem lies with them or with Shopify. I am using the Minimal theme.
