It looks like your mediapackage contains two tracks with the "preseter/source" flavor. This would be OK if one track contained a video stream and another an audio stream, but if they both contain an audio stream, we won't know how to disambiguate which audio stream to use in subsequent workflow operations. Rather than picking one at random we throw this error so you can quickly see that there is a configuration problem.
You should take another look at the capture agent configuration to ensure that it produces either one muxed track of flavor presenter/source, or two presenter/source tracks, one with only a video stream and the other with only audio. Of course you can include tracks of other flavors too, but the same rule applies: only one stream per flavor makes sense in a mediapackage.
