Fixed! AirThings WavePlus - Not Reporting Radon Levels

I recently added the AirThings BLE Sensors to one of my ESPHome devices and it seems to be working for all the sensors except for the radon levels. This device has been polling for about a day and a half now:

Has anyone else run into this issue? Were you able to resolve it?

Today I updated to ESPHome 2021.12.0 - 11th December 2021 — ESPHome and once the update was completed the radon values started showing up.
