Improper Midi File

I'm downloading midi and importing it into my DAW (FL Studio) but it's missing almost half the notes from the original score that's posted on the website. For some reason, it's only when I download it as midi. Whenever I download it as a pdf or audio, it's exactly the same as it is on the website.
