Hi Natalia,

  1. Yes it is normal.
  2. The order GRAD/MAG doesn’t matter, the sensors are processed independently.
  3. No you should not remove any component that do not match the type of artifact you are targeting. You need to go back to the list of events that were marked as bad and keep only the ones that clearly eye movements.
