RCA test example error

[whatshow]

Q1:
When I run ./waf --run "rca --seed=1 --simulationTime=60 --payloadSize=256" in the code you provide, there is error saying the TIM group number not equal to RPS element number

Q2:
From Q1, I add 2 parameters to fit the RPS settings in IEEE-802.11ah-ns-3/OptimalRawGroup/RawConfig-rca.txt as the command, ./waf --run "rca --seed=1 --simulationTime=60 --pageSliceCount=2 --pageSliceLength=1", but the packet loss is 82.26%. Is this packet loss normal or I did some wrong configuration?
