Reply to Spectra LED "problem"

Hi there,

I recently got my midi fighter spectra. I installed the midi fighter software and started to push the buttons.
I noticed that if I push buttons on the left sidethe LED pattern which lights up looks different to one thats triggered if I push the same button on the right side.

Is this intended or is this an error?
I made some sketches of the behaviour of the triggered pattern of the right side.
Blue - pushed button
red - triggered LEDs
question marks - different to the left side triggered pattern
