Is DGettext working properly?

[sinnrrr]

I have this file structure

And this in my dialogue.po file

msgid "Choose the day of the week ;)"
msgstr "Оберіть день тижня ;)"

When I am calling the foo.DGettext("dialogue", "Choose the day of the week ;)") english version is returned.
The normal translations are working properly, but when I try to load from other domain it just returns me what I typed in.
