Hi Wartin, thank you for your post, but to be clear:
this works through history of all PS since 1.3.0. -> up until all recent ones. I'm working with PS ever since 2011, never had this issue.
What I'm trying to say is that just Orders/Orders View Tab, thus far the only one, doesn't translate the headings etc.. as in picture. Everything else in TB translates well, whenever the translation string is valid.
Please be aware, that this is a fresh unmodified instance of TB 1.1.0 with the localisation imported from official library.
Could you, if you have the time, replicate this issue on your behalf? Literally any other language.
