Untranslated but not found

The listing All Projects LibreOffice master - UI says there are 22 incomplete words in Norwegian nynorsk (nn). They are found in sd (10), sfx2 (1), sw (1), and xmlsecurity (10). But when trying to list them I get "No results".
How to find them?
I am translating online. Have not checked if it is possible to find them offline.
