Stems Bouncing Issues in Pro Tools - Latest Bounce Factory Update

Hello

I'm reaching out because I have been using Bounce Factory for a while now and I started running into issues once I did the recent update to both SoundFlow and Bounce Factory.   Due to some routing circumstances within my mixing template, I typically print all of my stems through the 'Sel Track Mute Pass'  selection.  At which point I will say leave all my drum kit stems open and everything else selected will mute, and on down the line for the various instruments.   However, with the recent update it is doing something very inconsistent.  It will randomly open up different instruments for random stem passes (example:  I print my drums stem and its clean, I print my perc 1 stem and its clean, perc 2 stem will suddenly have Bass and EG 2 in it, then perc 3 will be clean again, EG 1 stem will have Piano, but EG 2 will be clean, Strings will have Bass and my Shaker stem too, etc...).  The behavior is not consistent and I doubled checked that there were no Mute automation points which would open up the Muted tracks as it bounces.

I've done my stems this way through Bounce Factory for over a year now and this is the first time I've encountered so many issues.  This has happened on every song I've tried to do stems on since the update (probably 6 songs).  Please help if you have any fixes. If I do a song with 26 stems, usually 10-12 of them have issues).  To be clear it seems like this is random every song (ie: if Perc 1 has this issue and Bass and EG 1 are also printed on it in Song A, when I print Song B, Perc 1 might be clean or have that perc item AND a different instrument like Piano on it).

Thanks for your help with this issue!
