By using POEdit, the generated file is just 18 strings and mostly from admin side. Also changing locale in short code to "fi" does not change anything and source code still shows "EN", all the calendar headings are in English and week starts from Sunday and timestamps are in 12H format.
EDIT: it was a cache issue with locale, but POedit does not still work and word "list" is not translating correctly.
