English buttons after update even 100% translated

Hi

I have a fully updated wp/woocommerce shop. After my last update, some of the translations are gone and it shows f.i. “Apply coupon”, “Update cart” or “Proceed to checkout” even though all the translations are good in the woocommerce-da_DK.po-file in the wp-content > languages > plugins-folder. It all should be in danish, but its not…..

It is driving me nuts ! Suggestions are very welcome.

Henrik
