Problem with option "copy as document link"

Hello,I have a little problem,

first I must say that I have a form with a filed “url” that keep a url type “http://…”.

when I use the option “copy as document form link” in a view of document created with the previus form, and later in a hotspot properties paste the link, write the url of the field, but it should write the link of the document.

If someone can help me, I do not understand what is happening.

Thank and Greetings
