RBE reduction during 3D playback

I am testing on the newest Beta firmware available to testers and when I try to enable RBE reduction mode in blu-ray frame packed content, I get the notification, that "Anti-RBE is not supported in 3D mode" Does this mean that it is competed on the development side, and will be released in a future FW or if not please clarify. Thanks

Anti-RBE function is supported in 3D mode.
