StudioLive Software Reference Manual-EN_V6_210220171, section 7 (available on the download page of your product)
Sorry, your question is difficult to understand. Have a look at the manual. There is a picture of Capture right at the top of the section, showing the recorded WAV-files and the metering below. To see the metering like this your computer needs to be connected to your SL/RM AI mixer via FireWire and your mixer has to be selected as audio device in the start menue. If an audio device like the soundcard of a computer is selected, the metering will only show the stereo signal.
What is different from what the picture shows and what you see..?
