Keyboard keys not Chromatic - MPC Beats/MPK Mini MK2 keyboard issue

[LevyRes]

In MPC BEATS my keyboard keys are not playing some notes chromatically.

I'm following the Beats academy tutorial and during the House video the presenter shows how to make the baseline.

At this point I noticed two or three notes in the octave are lower, why? What did I do wrong?

You might need to contact the person who made the tutorial to ask them what went wrong.
