It is how you are using the Autoblip. If you are just rolling off the throttle and using Autoblip it will do that because RPM be higher. If you are on the brakes close throttle with RPM on a higher range and matching it as down shift then there is no problem.
If you have woolich you can adjust the TPS opening according to your riding and what RPM you are down shifting. lower RPM range may need less opening.
