Not getting Bandwidth of 40Mhz in CSI data

[pampariumeshchandra]

I am trying to collect CSI data from 2 ESP32 Wrover B.By default it is showing 40mhz in the settings but when I am trying to collect the CSI data it is showing 0 in bandwidth(CWB) (0 for 20 Mhz and 1 for 40 Mhz). Could you please help me in finding the mistake.Below is the attachment of CSI data.

From where on the menu screen did you set the bandwidth from 40MHz to 20MHz?
