Camera Raw 3.7 Bug with Lightroom

After updating to Adobe Camera Raw 3.7, I discovered a bug that affects Leaf .mos files imported from Bridge - all metadata entered in Bridge with ACR 3.7 is stripped out of the files in Lightroom. Only the camera metadata (and for some reason keywords) will show up in Lightroom. Going back to Camera Raw 3.6 ends the issue. I have no idea if this affects any other raw formats besides Leaf .mos files, but if you run into this issue, try reinstalling 3.6 and then re-pasting the metadata to all affected files in Bridge and the problem should be solved.
