Impossible to insert metadata with PDFs from Finereader 12

I tried more than one pdf created with Abbyy Finereader 12 (last version). In attachment an example without OCR, but I tried also with OCR files.

There is no way to save with DO some metadata: in particular Tags and Title are not retained. Comment field instead seems ok. The pdf is v.1.5, which is not the last Acrobat version. Can someone explain?
