Background of the issue:
I am trying to ensure that the primary language of my site, which is German, displays correctly. After a recent WordPress update, translations from some plugins are showing in English for the primary language.
I have updated WPML and Woocommerce as it was suggested before reporting any issue. But it did not help.
The issue can be seen on this page: hidden link.
Symptoms:
Translations for the primary language are not working correctly, with some strings and buttons appearing in English instead of German. This issue occurs in the booking widget on the right side.
Questions:
Why are translations for the primary language not working after the WordPress update?
How can I fix the issue of some strings and buttons appearing in English instead of German?
