Kickstart Profiles and Satellite Proxy

I've been looking all over the place for information about Kickstart profiles and how to make them available via the Satellite Proxy.

Everything that I have found seems to indicate that if you make a new KS profile in Satellite, you should see that profile available in the Kickstart Boot Menu whether you PXE boot from the Satellite or the Proxy server.

In my environment, however, the Kickstart Boot Menu is completely different if I PXE boot from the Satellite vs. from the Proxy.

Does anyone know how to make KS profiles available from the KS boot menu on the Proxy?
