PS4 Strange Emergency Brake Application On Class 158

Hello,

When I was driving the Class 158 on the Midland Main Line - 2L20 Leicester to Lincoln Morning Service, I was running with AWS working. I was between Leicester and Syston Stations, running under the speed limit but approaching it and just about to shut off power and coast, when there was an unsuspected AWS Brake Demand so an Emergency Brake Application was made.
