No layar levell in windows

hi, I have a document consisting of multiple layers (text layers and image layers).
When I go View> Layers nothing is displayed in the Layers window. Why? What should I do to make them show? Thank you

Hello.
Normally, what you are doing should be enough to see the layers. Can you email the PDF to us, so we can take a look?
Please send it to support@iceni.com

hi, document sent.
Thank you
