Hi there @jrokov
Yep, I have the same issue here, it looks to me that Live 10 can't import those audio files correctly, could be a bug or lack of feature, not sure.
The original audio stems are 44100 / 32bit .wav files, when importing them in Live 10, playback will be broken, the wave form is completely wrong and the output level is fully saturated.
Converting those files to 44100 / 24bit .wav files and the import & playback worked as expected.
Changing File Type & Bit Depth in Live 10 settings doesn't help, still not working with original 32bit files.
Not happening in Logic Pro, so definitely something to do with Live 10 (tested in 10.1.5 as well as latest Beta ).
So you'll need to convert those audio stems to 24bit audio files.

Converted 24bit import result :

@Protoculture @Sonic_Academy Might be worth to include a 24bit version of the stems into the tutorial resources to avoid this issue.
