You can wait and see if Woo will update the language files, but if you don’t want to wait, various background reading and methods, including a plugin, are here.
Here is one method. I am using Spanish as an example.
Bring up wp-config.php in a text editor and look for the line:
define(‘WPLANG’, ‘es_ES’);
This will give you your language identifier, in this case its “es_ES”
Go to wp-content/plugins/woocommerce/i18n/languages
and look for:
woocommerce-es_ES.po
Rename it with a .txt extension so you can edit it.
Add a pair of lines at the end for each form label translation. The first is the English that appears now, the second line is the translation in your language. For example:
msgid “Company Name”
msgstr “Nombre de compa?ía”
Change the file back to .po and download it to your hard drive.
Compile your .po to .mo using this tool:
https://po2mo.net/
The converted filename might be:
h5673b_woocommerce_es_ES.mo
change it to
woocommerce-es_ES.mo
Ensure you get the underscores and hyphens right.
Upload the .mo to
wp-content/plugins/woocommerce/i18n/languages
overwriting the file that was there.
If you have a page caching plugin, delete cached pages.
