The imported pdf is exported as a black surface

I have imported a PDF page in the indesign document A4. Unfortunately, when I export the document as a pdf, the content of the imported pdf is displayed as a black surface. How can I fix this problem?

What is the content of the imported PDF?

DOes it apply to a standard? You should always import PDF/X-4 into InDesign.

Yes the imported PDF apply to standard. Is it possible that something is wrong with the export settings and thats why after the export the pdf is not schown correctly? It does not happen when I import an jpg.
