The deepl.Formality is ignored

The above code prints this:

text_1_plain
 
‘So you want this hung up in the window, my — in the window, miss?’ asked Mr Dunball.
‘If you could hang it up without inconvenience, sir.’

result_1_plain_default
 
Sie wollen also, dass das im Fenster aufgehängt wird, mein - im Fenster, Miss?", fragte Mr. Dunball.
'Wenn Sie es ohne Unannehmlichkeiten aufhängen könnten, Sir.'

result_1_plain_less
 
Sie wollen also, dass das ins Fenster gehängt wird?", fragte Mr. Dunball.
Wenn Sie es ohne Probleme aufhängen können, Sir.

result_1_plain_more
 
'Sie wollen also, dass das im Fenster aufgehängt wird, mein - im Fenster, Miss?', fragte Mr. Dunball.
'Wenn Sie es ohne Unannehmlichkeiten aufhängen könnten, Sir.'

text_2_plain
 
I am not angry with you, Edric.
"Thou art a brave lad!" cried the duke.

result_2_plain_default
 
Ich bin nicht böse auf dich, Edric.
"Du bist ein tapferer Bursche!", rief der Herzog.

result_2_plain_less
 
Ich bin nicht böse auf dich, Edric.
"Du bist ein tapferer Junge!", rief der Herzog.

result_2_plain_more
 
Ich bin nicht böse auf dich, Edric.
"Du bist ein tapferer Bursche!", rief der Herzog.

Looks like the deepl.Formality is ignored.

text_1:
"You" is always translated as "Sie", but should be "Du" if formality==deepl.Formality.LESS

text_2:
"with you" is always translated as "auf dich", but should be " auf Sie" if formality==deepl.Formality.MORE. The same is for "Thou art"
