Analog keys plugin output issue (logic pro x)

I am having a hard time getting my analog keys software instrument to act according to the output configuration I select for its plugin instance. For one thing I can add only 5 aux channels to the instrument, despite there being 6 outputs stated on several of the settings. The available output configurations also look odd, given I have the stereo L/R and four synth tracks selected in the overbridge control panel. Anyway I can get the four synth tracks with no issue, mono or stereo, but can’t seem to get the main outs going. Any other Logic users work through this?
