Translate button of top list of invoice

Hi,
I don′t fine words to translate for Draft, Unpaid, Overdiue…
I see some words have been translated, but not others in mSpanish, for example:

Todo (232) | Publicados (228) | Draft (181) | Cancelado (0) | Overdue (15) | Pagada (29) | Unpaid (3)

I can’t find these words: Draft, Unpaid, Overdue in the .po file

I think there is no chain created for this and I don’t want to touch the original file, without telling you because as soon as I update, I will lose the changes again

Can you help me please?
Thank you so much!
