Conflict with plugin Composite Product plugin by woocommerce

Hi,
in the past you plugin was working well togheter with Composite Product plugin by woocommerce (https://woocommerce.com/products/composite-products/?_ga=2.244465485.955039403.1579184226-1897098088.1575490737)

Since one of the latest upgrade (unfortunately I do not know which one), it stopped working properly.
When a user select a swatch variation, the composite product plugin does not recognize this choice and it return the error that a choice is required.

You can test it in the url I have included in this message.

Deactiving Variation Swatches plugig allows Composite Product plugin to work again properly.

Thank you for you support.
