2020 WRX base model problem?

Cobb Accessport was showing my AF Learning 1 going to -15 down to -30 at times. I finally found out it was my MAF sensor. Got it replaced and now this is where the riddle starts. My AF Learning is between -6 and +6 which is normal. But not I am getting Feedback Knock and Fine Knock Learning anytime I go into boost.

Question is... Is the car re-learning because the MAF sensor is working correctly now? Or is that nothing to do with it?
