Difference audio waveform in different Premiere version.

Hello! I have two files. First file (1-original.mp4) is original file, the second (1-ffmpeg-remuxed.mp4) is processed throught special utility.

I open this files in Premiere. But in the different Premiere versions I see different waveform for the same file.

In the Premiere 13.1.4 build 2, I see strange shift in the begin of the file

But in the Premiere 14.0.4 build 18, I see good waveform

Why Premiere Pro 13 has strange shift in the begin of the file?

There is my example project https://drive.google.com/open?id=1mD0fmruDobG_DCM-3nfPw8XP-qPFsqON
