OJS - QuickSubmit Plugin and Galley locale

Dear all,
after a long time I upgraded to OJS
The journal is a multilingual one with English (primary locale) and Italian.
I have a problem with QuickSubmit Plugin (we do not use the entire OJS workflow to publish the issues).
I want the label “PDF” to show both for English and Italian.
When I add the galley, I have to choose the language. If I choose English, which is the primary locale, I get “PDF” for English, and PDF (ENGLISH) for Italian.

I would like to solve this problem but I can’t find a solution.
Thank you in advance.
