When importing midi, notes will duplicate and cause cut off.

Hey,

I randomly start looking thru midis just to start an idea and came across a folder with some piano midis. Whenever I drop and drag them in, any time there is a long note, there will be one or multiple 'stab notes' inside that same note that will cause it to repeat and then cut off the sound.

Any idea how I can import midi's without having to look thru each note and make sure it's not repeating? Any insight would be appreciated!
