If you want a Parallel root and have its children repeat forever, may I then suggest to use a Repeat “forever” decorator at each child of the Parallel like in the image below? In this case the “Repeat” option in the Parallel has no effect and the Policy is also pretty much irrelevant since the decorators repeat their child nodes forever.

Let me know if this is the behaviour you are after.
