Variant selector issue with 2 options, causing the shop button to be inactive.

The problem I’m facing is as follows: When I select “Variant 1” of a product and then proceed to select “Variant 2,” the purchase button becomes disabled, preventing me from completing the purchase. It’s an unexpected behavior that I’m having trouble understanding.

To provide a specific example, when I choose the “Black” color option for a notebook and then select the “Dotted” pattern, the product becomes unavailable, and the purchase button remains disabled. However, I’ve noticed that if I first choose the “Dotted” pattern on a “Black” notebook, then switch to the “Green” color option, and finally return to “Black,” the purchase button becomes active again, allowing me to proceed with the purchase.

I’ve tried this on multiple occasions and even on different devices, and the behavior is consistent. It seems like there might be an issue with the interaction between these specific variant selections.
