I have an issue converting files with libreoffice.

Saving a .doc or .docx file as .odt, creates a folder (inside the chosen one) whereas both (file & folder) renamed to: multiple ?? and extracting an .odt file as .pdf creates only a file into the chosen folder renamed to: (file name)???

I asked also to libreoffice forum but there is no answer up till now (if there is an answer - solution I`ll notify - inform the community).

Any ideas?
