Audience + CAPsMAN always 160MHz

My Audience just arrived today, tried to set it up in CAPsMAN but found the 2nd 5GHz radio always do 160MHz, I just wanna use 80MHz but impossible to do so, in the channel setting I selected Ceee but no luck, and CAPsMAN has no setting like Ceeeeeee for 160MHz as normal wireless tab do. Is CAPsMAN not yet ready for Audience?

I wonder how those RB4011 user do since they are the same QCA9984, can u guys set it to 80MHz in CAPsMAN?

Thanks

Solved, by setting secondary frequency to 0
