Auto-apply offline processing doesn't work with iZotope RX9

C12, Mac, RX9 - when I’m using RX9 Connect in Direct Offline Processing, the changes I make to the audio file in RX are not applied to Cubase if Auto-Apply is checked (is this a glitch or a compatibility issue?). I don’t see any way of overriding auto-apply aside from disabling it which does bring up buttons for Apply / Cancel.
