I have a Pressbook in which I have set the book’s language to “English” (in “Book Info” configuration page), however, figure caption language remains “German”. I cannot find other means to affect the book’s language in the available settings (I have also set my personal language to “English”).
I have also tried to start with a clean slate but the issue remains - I cannot affect the figure caption language.
Looking into the manual gave no avail, I was not able to resolve this issue.
As you probably guessed, I am new to Pressbook’s but as far as I understand, it uses WordPress under the hood. For the latter there must be further templating options. Is this the right direction to look into? Do you have any other hints how to resolve it?
Thank you very much for your insights.
