C13.0.20 - Bounce Selection Time estimation is way off

There are possibly some variables involved, but in my current project, where I use chunks of longer (20min.) audio file in musical mode (120bpm originally, 106bpm at the moment in question), when I’m trying to bounce a short chunk n order to bake some of the processing and weird artifacts (like waveform not matching audio, or copying a short chunk will shift the result audio part by minutes…), the time estimation in the progress window is way off:

It would estimate 20 or more minutes, but is done within 15 seconds. When it’s done, the progress bar shows 1% finished. Other times, it will finish at progress bar still showing 0% copletion.

Could it be a math mistake in the code, and the 1% should in fact be 100%? (100% being 1 whole - therefore the 1%?).
