WooCommerce strings are not translated

Hi

I am currently re-building my webshop, Using the Enfold theme and woocommerce. I have the problem that the woocommerce text strings are shown i English and not Danish (my native language). The overall wp language is set to Danish.

I’t seems that advise on this problem is to ‘force translation’ in woocommerce->system settings->tools. However this option is not available – the woocommerce version I am using is 2.52.

My old webshop was based on the free theme Mystyle from woocommerce.

The two webshops are setup in similar ways. Here is one example of the problem:
New webshop:

Note: the missing translation is a problem on both the front-end and the back end. It seems to be a problem for other plug-ins too.
For the native Enfold theme functions, both the back- and front end is working well in Danish.

Thanks for helping me out :)
