Have you moved qualities around? If they are still in default order (e.g. 1080p qualities at the top, 720p below that, dvd and shitty qualities below those), it should work based on your description of the profile.
I feel this image/text is still relevant, even with v3 now: Asking for confirmation of sonarr logic
Second question, probably not applicable: after importing, the 1080p files are recognized as 1080p by sonarr, right?
