RESOLVED Logic Pro X 11.2.2 - Bounced files around 6dB quieter than playback

** Resolved - this appears to a bug with Sonarworks **

I've seen this problem asked about a few times but has any one found a solution?

Now in Logic 11.2.2 bounces are around 6dB quieter than when playing back in session compared with 10.7.9.

Nothing is clipping, the master fader is at 0dB, Normalisation is turned off and the Ozone Maximiser on the stereo bus has a ceiling of -0.5dB yet the bounced audio is averaging at around -6dB as if no Maximiser was used (Gain Match is also not turned on)

I've looked through but cannot find any settings (both Project and General) that would cause this issue.

Does anyone have any ideas?
