[Gelöst] WooCommerce default language became English

Background of the issue:
I have installed a site with 4 different languages, with Norwegian being the default language and Swedish, Danish, and Finnish as additional languages. Each translation has its own TLD: *.no, *.se, *.dk, and *.fi. The issue can be seen at versteckter Link.

Symptoms:
I expected to see Norwegian language for WooCommerce under the *.no domain, but instead, I got English.

Questions:
Why is the WooCommerce default language showing as English instead of Norwegian on the *.no domain?
