Max range of Probe Volume component doesn't update to global max

Repro:

1. Add a Probe Volume component to the Scene.
2. Ensure the Max Probe Spacing slider is set to the fourth position, which defaults to 243m in the Probe Volume tab of the Lighting window.
3. Select the Probe Volume component. Enable "Override Probe Spacing" and set the range slider so that the max range is at the rightmost position in the slider.
4. Generate Lighting

Observe:

The max range of the Probe Spacing slider component does not update to show the new global max range of 243m. It remains stuck at 27m. This makes it impossible to override probe spacing to be within the last 2 subdivision levels.

 

Expected:

Override Probe Spacing should offer ranges within the global min/max set within the Lighting window.
