Hello,
I have checked the product http://prntscr.com/lkeegh I see swatches and they work.
Please make sure you have:
1. Dashboard -> Products -> Attributes -> Color -> Configure iterms, enable swatch as shown http://prntscr.com/jskm29
2. Navigate to Theme Settings > Shop > Attribute swatches > choose pa_color (your color attribute) and enable “Use images from product variations”
3. Make sure each variation in a variable product has an image: http://prntscr.com/kk870w
