Less likely, but possible, is a problem with the Gerber viewer/editor. What Gerber editor/viewer are you using to look at the Gerber files? What does the aperture table in the Gerber editor/viewer say for the aperture that should show the thermal?
It may be that your Gerber viewer/editor isn't reading the aperture properly.

Hello All,snip
I have a PCB design that has several ground planes in it. I have all of
the ground vias directly connected to the planes. I have all of the
thru-hole components grounds connected using thermal reliefs. If I look at
the PCB with the internal planes tab selected and with the multi layer view
option turned off, I see the thermal reliefs.
When I generate the gerbers using the embedded apertures (RS274X), most of
the thermal reliefs are gone. This only happens with the power planes. I
have several polygons in this design and their thermal reliefs are intact.
Has anyone else seen this? Does anyone know what I am doing wrong? Any
information that you can give me will be greatly appreciated. Thank you for
your time.
