"Level" sensors not reporting

[Nuuki9]

Environment

• Home Assistant Core release with the issue: 2023.5.0
• This custom component release with the issue: 1.6.3
• Last working this custom component release (if known): Unknown
• Operating environment (Home Assistant/Supervisor/Docker/venv): Docker

Describe the bug

The level sensors are all showing as Unknown. The index sensors all show data as expected.

Steps to Reproduce Configure the integration to include both level and index sensors. Confirm that an index is being reported as expected, but that level is "Unknown".

Expected behavior

Each configured area should have a sensor for the index (showing a number) and the level (describing the AQ).
