__from sequence audio exports aren't queuing up in encoder...?

I originally posted this in the media encoder forum but no one had any solutions so hope it's alright to post here...has to do with premiere sequence and encoder.

Just recently, the encoder isn't queuing up audio exports from premiere sequence. I'm exporting mp3's 128kbps.

It's worked up until now. Video's still queue but for whatever reason audio's are not.

Any suggestions?

Thanks
