Examples showing Turkish words in German LibO

Language mix: Using German installation, there are Turkish words at the top of the window after opening a database:

1. choose "Tabellen", choose any table (bk_bill), double-click to open the table in edit mode, the window headline tells "Tablo Veri Görünümü" instead of "Tabellenansicht" or so (upper part of the attachment).

2. choose "Formulare", choose any form (Buchungseingabe), right-click to open the form in edit mode, the window headline tells "veritabanı Formu" instead of "Datenbankformular" or so (lower part of the attachment).

Current environment: Windows 10 Pro (64 bit) and LibreOffice 5.1.6.2
Build-ID: 07ac168c60a517dba0f0d7bc7540f5afa45f0909
CPU-Threads: 4; BS-Version: Windows 6.2; UI-Render: GL; 
Gebietsschema: de-DE (de_DE); Calc: group

As far as I remember the same problem occurred in an earlier version of LibreOffice (4.4? on Windows 7 Home Premium 64-bit) but not in 5.0.4.2.
