CSV report no longer produces mean, median and other calculated stats

I updated gradle-profiler version to 0.15.0 from 0.12.0. I noticed that build time calculations such as mean, median, standard error etc are no longer being reported in CSV report.
command that I use for build benchmarking is rather simple one

 gradle-profiler --benchmark --scenario-file build_performance.scenarios --warmups 1 --iteration 5 

Here is my build scenario file

# Can specify scenarios to use when none are specified on the command line
default-scenarios = ["assemble"]

# Scenarios are run in alphabetical order
assemble {
    # Show a slightly more human-readable title in reports
    title = "Clean Build Debug"
    # Run the 'assemble' task
    tasks = ["assembleDebug"]
    cleanup-tasks = ["clean"]
}
