Thumbnails can either be stored within the file, or produced from the
proper image data. At some point, a thumbnail was stored in your image
file, but not updated when the proper image was changed.

There are programs designed for specifically removing thumbnails, or
metadata to be exact:

Or, you accomplish much the same thing by saving the jpeg as a 24- or
32-bit BMP file, then converting that back to JPEG.
