You need to apply a template to the file you're combining them all into.

If the file already has a template applied, then I suspect it wasn't created
correctly and the slide background was just added to the slide and not to
the master slide. See

and http://www.indezine.com/products/powerpoint/ppcreatemp.html for
information on creating templates.
