DocX to Epub convertion -> NCX-identifier does not match OPF identifier

Hello,
I saved an epub file from a docx file and validated this epub against http://validator.idpf.org/application/validate

It says:

NCX identifier (‘uid’) does not match OPF identifier (‘urn:uuid:eda164b8-9aad-45aa-95cc-1784901b9871’).

Then, I looked inside the epub and found out that these values are different:

NCX:
ncx.png (14.7 KB)

OPF:
opf.png (25.8 KB)

Is it possible to set these tags to the same value so that the epub can be validated successfully?

Thanks in advance,

Daniel
