Unable to copy a link to a sharepoint location in a field created as Text - Content: Hyperlink

Is there a reason why I can't copy a link into a property defined as Text and Content = hyperlink.

I am trying to copy/paste this file location into this field, but it will not let me.

It will let me paste it onto a regular text property but not to the hyperlink one.. is there a reason for that?

Regards,

Irene
