Hello,

After / Before add to cart button area is totally custom feature which relates to our theme only. That is why WPML support could not suggest anything as they just do not have any instruction.

You need to create two HTML blocks for each language and navigate to WPML > String Translation > Choose the admin_text_woodmart_option from the dropdown and find the title and the content block http://prntscr.com/lx5qpz

Please contact us on the issues related to all the customized features translations.

Best Regards
