Imported MIDI grooves are being quantized

I am trying to import MIDI grooves that I downloaded from ‘Grooves From Mars’ but when I import the MIDI file the notes are not nice and random like they should be (slight variation and off-grid notes). I want to drag onto my quantize window to save them as groove presets but the notes/groove is somehow being snapped on import. I have quantize off and AQ off as well. Please help this is driving me crazy! Thanks
