So after a bit of digging, I found that one file was not transferred properly bc it was a LR virtual copy. And then a bunch of other files didn't make it over with saved LR keywords bc they are Fuji x100s Raws. I needed to upgrade my Adobe Camera Raw to 7.4 or higher in order for Bridge to be able to read them. Oddly now I'm having the opposite sort of problem in which my Bridge collection says I have over 200 photos in it but the corresponding LR collection says 175ish. But I'm okay with that bc I can sort it later. Just wanted to update in case anyone runs into this issue.
