Hi Marcia.
This is a known issue: raster without a colour table are not given a
default one: https://trac.osgeo.org/qgis/ticket/1207
We are working on this:
http://www.qgis.org/wiki/index.php/Bugs
I allocated some resources to hire a dev to fix it, and I expect it will
be ok soon.
Of course, you and other users are encouraged to add some resources to
the budget, so more bugs will be fixed.

This may be a new bug. Please test it carefully and open a ticket for this.
All the best.
