Warning on package regarding Material Baking

Hi

I was going through the complie log from the latest build/package and there was a couple of warnings that came up:

UATHelper: Packaging (Windows (64-bit)): LogInit: Display: LogConsoleManager: Warning: Console object named ‘MaterialBaking.UseMaterialProxyCaching’ already exists but is being registered again, but we weren’t expected it to be! (FConsoleManager::AddConsoleObject)

UATHelper: Packaging (Windows (64-bit)): LogInit: Display: LogConsoleManager: Warning: Console object named ‘MaterialBaking.SaveIntermediateTextures’ already exists but is being registered again, but we weren’t expected it to be! (FConsoleManager::AddConsoleObject)

Just wondering if anyone can shed some light on what these mean and how to go about fixing them, as far as I can tell all the materials complied correctly during the build.

Thanks
Daniel
