Cannot copy and paste from a database word document

When I open an existing word document and copy text and then go to Create/Object/microsoft word doc, and then check the box for “display as icon” then change icon/ok I cannot paste the text that I’ve copied from the original to my new word document. Now if I keep the existing one open while copying and pasting it will work, but if I close the existing one after I’ve copied the text I do not get the option to paste.
