2021 Premiere Update - No Audio on Timeline, Waveform present

[Matt Forgey]

I just updated Premiere to 2021 on MAC. Opened a project from the day earlier now all my cut audio on my timelines wont play with sound??? The waveform still shows on the timeline, when you open the audio file in the source window it has sound. Outside of premiere it has sound. Only on my timeline is it broken?? 

I've tried changing Audio Hardware presets, I've tried copy and pasting into new sequence and as a new sequence. I've deleted my cach fiiles... I've basically done every youtube tutorial I can find and still no luck. I even converted my wavs to mp3s and reloaded the audio. Nothing works. Please help, losing my mind.

FIXED THE ISSUE!!! 

The was an unkown Fill Left effect on the audio in question. Removed it and it's back baby!
Now to figure out how THAT got there...
