Inserting pdf file as icon - cannot get picture to show up

[patrick_james]

When I insert a PDF file as an object and select it to display as an icon, it
is not showing the pdf picture/icon in the document - only the caption shows
up in the powerpoint slide (depsite the pdf icon being selected in the
"change icon" screen when I insert the object).

Does anyone know how to fix this so the icons show up as a Adobe picture
with the caption below it like it is supposed to do?

I don't think I've ever had the PDF show up as a true thumbnail in this
situation -- it's always just the PDF icon.

What is it you need, exactly? Is it just to display the PDF during slide
show view? You can do that with an animation setting. Select the PDF icon
and on the Animation Pane, choose Add Effect. Select Object Action | Open
and specify that it start automatically, which will open the PDF when you
come to that slide.
