FCPX- Audio Randomly cuts off at end of clips...?

Audio randomly cuts out at end of random clips BOTH WAVEFORMS AND SOUND. It is random. I have deleted my render files, deleted my peaks data in fcpx library file. When I delete the files the audio comes back on some clips and not others. Has anybody heard of a solution for this. There was another forum for this but they never came to a solution. Any help would be great! This started happening in the last few FCPX updates.

This happens on majority of my footage. All my footage is transcoded from RED files and the audio can be heard correctly in quicktime...I checked. Yes my files are transcoded correctly.

I am on MacBook Pro 15inch, Mid 2014, macOS High Sierra, FCPX 10.4.3.

What are the hard drive specs the Library and media are on?

Does system dive have at least 15% of total capacity left as free space?
