Marimba from Bell option changes to Midi option

[ej-sanmartin]

So I was listening through all of the instruments to see which would sound good for a song and I notice that when I click on the Marimba instrument from Bell option, it changes the option from Bell to MIDI. This is nitpicking and would probably have something to do with perhaps the Marimba instrument uses the same sound clip in both the Bell and MIDI options so they are connected in that way.
