Thanks for the link Mike, the procedure outlined did the trick. Site and woocommerce now fully translated.
Hi Stephan,
Thanks for getting back to me.
My site is not live, I am developing a site locally.
I manged to get the category (containing the specific subcategories), to show on the shop page, by adding a dummy product to it, after deleting the dummy product the category stayed visible.
Very strange, maybe a bug.
