Repro:

Create a new project using the HDRP template in version 2020.2.0b9
Open the Scene "SampleScene.unity"
Navigate to the Light Explorer (Window > Rendering > Light Explorer)
Find the column "Shadows Resolution Level"
Open the drop-down list for any entry in the list of Lights

Observe:
The available options are Custom, Low, Medium and High 

Expected:
The list should also include the "Ultra" option which is available as a default in the HDRenderPipelineAsset.
