Face Refinement and Rotation

I have footage that is shot in portrait mode, this imports 'correctly' on its side into the timeline.
I want to use the Face Refinement plugin which will only work if I rotate the image 90ยบ to analyze the footage; I can then use the refinements and rotate the image back to it's correct orientation.
Is this correct or is it a bug ?
On occasion the correction works on the first frame only.
Is there something I am doing wrong here?
Finally my delivery is as expected, which is fine for the client but how do I make an output in the correct visual orientation. ie a portrait format, Digital Escalator Panels.
