Unreal Engine Issues and Bug Tracker (UE-45638)

Description

When selecting an actor in the World Outliner that is using the ColorGradingMode specifier (ColorGradingMode = "saturation"), the editor crashes.

This did not occur in 4.15.3. This is a regression

Steps to Reproduce

Open the editor
Create a new C++ Actor class

Add the following to the header:

 UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "PostProcess", meta = (UIMin = "0.0", UIMax = "2.0", Delta = "0.01", ColorGradingMode = "saturation", ShiftMouseMovePixelPerDelta = "10"))  
 FVector4 colorSaturation;

Compile
Place an instance in the level
Select the instance in the World Outliner

Result: Editor crashes
