Polylang integration

Hello,
I use the last version of Understrap Child Master modified.
“Understrap CM + Loco Translate + Polylang + Polylang Woocommerce Hyann Integration” works perfect. I jsut have a little translation problem and I think it causes by theme because everything looks on Ok on Loco Translate and Polylang.

As I catch till now “Cash on Delivery”+”Pay with cash upon delivery.” sentences in the last order screen looks are not translated. I couldn’t find specific template of these pages, probably they can’t read the translated data from Polylang or vice-versa.

Can you help me ?

Thank you.
