I’ve just bought Improved Variable Product Attributes for Woocommerce. According to plugin’s author it should work with Legenda, but it doesn’t.
This plugin displays simple product attributes as variations in variable products. See https://tshirt-gallery.pl/produkt/zestaw-koszulek-dla-par-piekna-bestia-01/ You can choose size and color of t-shirts. This plugin doesn’t allow to add product to the cart until all required attributes are selected. It works well with Storefront. If some options aren’t selected you can’t clik add to cart button (but you see it). With Legenda the checking process is ignored and you can add product to the cart without selecting any options. Moreover, on shop page there are add to cart button instead of “select options” buttons and of course you can buy products with no options.

We have checked product with the default theme and we were able to add to cart even with the default theme https://gyazo.com/be6340cd0cfc6b887a935649113d0e87
The only difference was the cursor and button color. I have added the same styles as the default theme has.
So, contact the plugin author about the problem.
