Recording with Mosaic confuses audio tracks

[slimjim]

I am using a Mosaic script to merge four video and two audio sources into one stream / file. The audio input appears in two different tracks (which is good), but I the track allocation appears to be arbitrary. Without having anything altered in between, audio source A appears in audio track 1 in one session and in track 2 in anothersession, while source B appears in the other track respectively. I have no idea how I could manage to reliably allocate one audio source to one audio track. Can anybody help?

I am using Windows 7 64, but I'd expect that this issue should be independent of the OS.

This is my mosaic.conf:
