You got DeviceGray either because this is the default colorspace for stroking
and non-stroking, or because it is set in the content stream (I saw "0.0039 g"
- you can see that with the PDFDebugger command line application). What you saw
with Notepad++ is the colorspace of an image.
Stroking is lines, curves etc. Non stroking is filling stuff. (Both also apply
to text; usually it's the non stroking color) Images have their own colorspace;
in your file, the colorspaces that are set are irrelevant.
This is your content stream of the first page. Open the PDF 32000 specification
and search "operator summary" to see what the operators (q, cm, rg, g, Do),
mean.

I'm closing this as not a problem because whatever the original problem was, it
has already been solved. You're lucky, the 2.0.4 version is planned to come out
next week.
Btw, if you ask questions to the user mailing list, you must upload PDF files
or screenshots somewhere, e.g. dropbox, google drive or a sharehoster, because
attachments don't get through.
