Eclipse FAILS to preserve project Configuration settings in CDT

Question

I am working with Neon Eclipse. I have a number of #ifdefs in the project that I am working on, that require Project Settings to set up the Symbols for numerous configuration options, and those configurations will change based on which system I am testing or developing on. I created a new Configuration for the device that I am working on, and set a number of these for that particular configuration, and set that configuration as the ACTIVE configuration. Eclipse has a nasty habit of crashing frequently, and when I restart it, the configuration that I created, fails to be displayed. I can see all of those symbols, in my .cproject file as shown:

<storageModule moduleId="cdtBuildSystem" version="4.0.0">

                </tool>

However, I am not seeing the name of the Configuration that I created and set as Active. Why is Eclipse doing this, and what can I do to make it behave properly?
