Device_tracker shows nothing when track_new_devices: no

Hi all, I’m trying to configure my system to only track my 3 phones. I have them set up in known_devices.yaml and configuration.yaml:

Configuration.yaml snippet:

device_tracker:
    - platform: ddwrt
    host: 192.168.1.1
    username: !secret ddwrt_username
    password: !secret ddwrt_password
    track_new_devices: no

  - platform: owntracks
    max_gps_accuracy: 200

known_devices.yaml:

tauceti:
  hide_if_away: false
  icon:
  mac:  AB:CD:EF:34:F0:AB
  name: Rene Robinson
  picture:
  track: true
  vendor: Apple, Inc.

karen_robinson:
  hide_if_away: false
  icon:
  mac:  AB:CD:EF:C5:32:61
  name: Karen Robinson
  picture:
  track: true
  vendor:

When I look for ANY device none are detected. The minute I change the setting from track_new_devices: TRUE it works, but scans and reloads all the devices on my network with tracking set to FALSE.

What am I missing??
