On Q3793400 (a book) the P364 (original language) is set to Q9027 (en:Swedish language, it:Lingua svedese), but both ENWP and ITWP returns Q298714 (en:Swedish, it:Svedese). The same property on SVWP returns Q9027 correctly.
As far as I can tell this is not a bugged.. Q3793400 has the articles [[en:The Hundred-Year-Old Man Who Climbed Out the Window and Disappeared]] and [[it:Il_centenario_che_saltò_dalla_finestra_e_scomparve]] When adding {{#Property:P364}} to each of these articles they correctly the relevant Label (Not Article) for [[Q9027]] which is 'Swedish' for en and 'Svedese' for it!
If you still feel there is a problem feel free to reopen!
