Invoice PDF field error

Version : 1.5.5
Language : Romanian

Where is highlighted with yellow, it should write CIF (Cod Identificare Fiscala), not TVA. In the client area, the field is marked as it should be, with CIF. Only in the Invoice PDF it is messed up.
Haven’t made any modifications to the default files.

Anyone? Just point me in a direction, what to edit and I’ll do it myself …
