Variable Products & Swatches

Hello, I hope you are well.  You have offered support to me on this topic before.  Everything was working correctly after that support and then suddenly things are not working as expected.

Here is a link to a product: https://freshprintsmiami.com/products/hallelujah-shirt/

I want the product swatch to change colors as my customers select different colors.  Currently, they have to select a color and also select a size.  Like I mentioned, you helped me fix this before, but something changed and now I’m having this problem again.  Please help.  Thanks.
