it appears to be a graphic bug...
attempt to render an mp4 (Mainconcept AV/AAC) file from the timeline. On the audio tab choose something other than 6,000 Bit rate (bps), move to another tab and then back to the audio tab.
For some reason on my system it reverts back to 6,000; however if I press OK in the description box it says Audio: 256Kbps the choice I'd made....
so I don't believe this is critical, just an annoyance,
