Variations are not displayed

I have products with 2 attributes:
– size: XS, S, M (value)
– color: white, black (image)

Size is set as standard variation attribute (I don’t have a separate product for that and I’d like to leave this as it is). Every color is a different product. And of course every product with different color has 3 sizes.

I followed both available documentation videos, but I’m unable to get plugin working as expected.

When I configure color what I get is just attribute name (Color: White) displayed on product page, without image or ability to change color. When I checked the code it looks like that:

<div class="woo-linked-variation-wrap"><div class="woo-linked-variation"><div class="linked-variation-label">
<strong class="variation-label">Color: </strong>
<span class="variation-selection" data-variant="White">White</span></div><div class="linked-variations"><ul class="linked-variations-buttons"><li class="linked-variations-item" data-variant="Black"></li><li class="linked-variations-item" data-variant="White"></li></ul></div></div></div>
