librewriter export as pdf issues

i have a file with some pdf inserted as images but wwhen i export to pdf all the document some pdf are rotated why?

  1. This is a question-and-answer sour site about LibreOffice. For librewriter (whatever it is), go to a respective site. Or spell the name correctly.
  2. When you have problems with a particular file, share it.

Is not only for a file is for all pdf i think is a bug.i think this is the right site.
