WooCommerce category widget does not work when "Language URL format" set to "Language name added as a parameter"

Overview of the issue

Steps to reproduce:

• Install WooCommerce with WPML and WooCommerce Multilingual
• Translate few products with categories.
• Set Language URL format to query string in WooCommerce Multilingual
• Drag WooCommerce category widget to sidebar
• Go to the category archive page other than default language. And try changing category it will take you to home page due to wrong URL.

Expected results:

• Category should be changed.

Workaround

This was fixed in WooCommerce Multilingual 3.6.5-beta1 available form the WPML.org downloads page.

This required a modification in WooCommerce. It’s going to be available in the next release after 2.3.11.
