As with any software related item, there are times where a good old reboot is needed! Your TV, ,PC and now an SDR radio! Was using radio for a time, then decided to listen to CW the ran into performance issue. No issues after power cycling.
Update: Apparently Noise Reduction (NR) and CW Decoding not compatible as noted in manual.
