When you save in Illustrator with PDF compatibility you are really saving a PDF along with the Illustrator paths, and that's the part of the file that ID is seeing. Although your illustrator file has only one color space, PDF in general can contain objects in multiple spaces (as can ID), so no color information is listed for PDF. What you are seeing is normal.
