No Pulse Ox fields

This is my first night using the device, and I see no Pulse Ox field in Garmin Connect.

Am I looking in the wrong place?

Device software:

Host: 3.70
SNS: 35.10
WHR: 21.01.00
BMX: 21.01.00
SoftDevice: 7.00.02

EDIT: Do I need to have the "Blood Ox" option on my watch set to track during sleep, for the Sleep Monitor to do so?
(I won't have the watch on during sleep)
