Product title, shipping and payment methods are not translated in WordPress WooCommerce new order email

  Kiến thức lập trình

I’m working on bilingual (Armenian and Russian languages) WordPress based online shop using WooCommerce plugin and stucked with translation for product title, custom shipping and payment methods titles to secondary language (Russian). The whole email, sent to customer after checkout, is translated except these 3 strings, they appear in Armenian. I’ve added translations on product and checkout/ page using TranslatePress web interface, but these translations does not work in emails. Web site interface displays all translations properly.

I’ve tried to ask for help on TranslatePress support page, but tips from there haven’t helped.

Could anybody help with this please?
