Camera RAW doesnt save AUTO Adjustments in XML files unless I click on each photo

My workflow is this:  Shoot 1000+ photos in RAW.  Open them all at once in Bridge -> Camera RAW.  Select All.  Click "Auto".  Drag Highlights to 0, Shadows 10 95.   Right-click a thumbnail and save them all as JPEG.  Click Done.    Then I go through the JPEG's and select the few good ones, and move their ARW (Sony RAW) and XML files to a separate folder for editing.   However, at this point, when I reopen these in Bridge -> Camera RAW, the XML file doesn't contain the "Auto"-button adjustments.   The issue is that I have to select-all and click "Auto" again .. and any manually adjusted individual pictures, this second "Auto" wipes those adjustments and I have to adjust them all over again.   On smaller batches where I adjusted a lot of pictures, on the second open I have to find the un-adjusted pictures and manually click "Auto" on each one of them.  A lot of labor.

I've found that if I put a heavy object on my right-arrow key and let Camera Raw scroll through all the thumbnails, then the "Auto" adjustments are saved when I click "Done".   However, this eats up a lot of time so I can't always do this before bedtime, when I convert to JPEG.

Is this "not saving Auto" a feature or a bug?   Or am I not understanding how "Auto" is supposed to work?
