Change language in Woocommerce

Hello

I have downloaded the danish translation of woocommerce. But there is some words, that have not been translated.

Do you know, how I manually can change them?

Here are some pictures:

And I also have the points and reward extension.

I have also downloaded the danish translation. But in the my account page it is still in english. How can I change that?
