RTC not supported by Code Generator

Dear friends,

I am using CS+, i tried to generate code for RTC by code generator option, when am click the RTC icon tab it show like that all are disabled. Even though 

i selected "Use" option, but all other thing looks disable. My controller is RL78/G13  R5F100FA.

And this function is not automatically generated in code "R_RTC_Get_CounterValue(struct RTCCounterValue *counterreadval)".
