2003 silverado 5.3 (scan tool question)

Hi guys, I have an actron cp9185 scan tool and tried to look at the o2 sensor voltages. The tool is only showing bank1 sensor1
bank2 sensor1 I was expecting to also see sensor 2 for both banks, anybody familiar with this scan tool and seen the same thing?

for the majority of work looking at down stream sensors is of no use. All they do is monitor converter efficiency and lightly affect long term fuel trim
