Windows Server 2012 R2 GPO Software installation Platform Mismatch

As seen in the image, using the latest release candidate, Group Policy Management seems confused as to the platform type. The x64 (Win64) package is displayed as an x86 type. Furthermore, under the Deployment tab > Advanced... button, the checkbox "Make this 32-bit X86 application available to Win64 machines." is checked.

I just tried the stable release and it does the exact same thing.
