Show items from subfolders hides jpegs?

So I had exported a few jpegs from their raw files using Adobe Camera Raw. They would show up in my windows finder, but in Bridge, they were invisible. Expect for one, which was made via Adobe Photoshop. The others, made through ACR, would not. I tried various things, but nothing worked, until I checked, "Show items from subfolders". Then, the jpegs showed up. However, those jpegs are not in a subfolder. They are in the same folder as their raw files. What gives here?
