Audio/sub track change when skipping around timeline

[BoomerJuice]

I've added some audio and subtitle tracks to a blu-ray with tsmuxer and BDedit and whenever I skip around on the timeline, the audio and subtitle tracks return to default. When I play the m2ts it's fine and maintains the same tracks, it only happens when I load up the whole disc and go through the menu. The new audio track is about a second longer than the original video so I've adjusted the out time to compensate but I'm not entirely sure what else that could affect... I'm pretty new to BDedit so I don't know my way around the program very well, is this an issue that's popped up for anyone else? I'd appreciate the help.

Mark the new tracks as default and maybe remove the original tracks if not used...
