BUG: Delay Compension Lost with Side Chain Compression

NI Battery is sending drum pads to multiple outputs, so assume the kick is coming out on 3/4 into a new aux track and then sent to a bus. Then add a bass softsynth to this session. When I put a Logic compressor on the bass and side chain it to the kick bus track, the timing of the bass gets very very messed up. It sucks big time. I was hoping that this would go away when I moved to my newer laptop, but no such luck. Any insights? Note: Delay Compensation is set to All.

UPDATE: On my current mix, I moved my kick to the instrument multi's main track and transferred what was there to another aux. This fixed the problem. So this proves there is a real bug. Side chain compression gets screwed up when the source audio is the aux output of a multi instrument. My work around will be to always keep my kick drom on the 1/2 (main) output of a multi instrument such as Battery. Not a bad compromise, but Apple should be made aware of the aux problem.
