Changing default value of an Enum in blueprints causes child Enum to change

If the default value of a child Enum variable is the same as its parent's value, any changes to the parent's default will also change the child's default.

1. Open UE4 Editor (any project)
2. Add two blueprints (BP1 & BP2)
   • BP1 is based on Actor
   • BP2 is based on BP1
3. Inside BP1 create a new variable of type EBlend Mode
4. Compile
5. In BP2, set Enum default to Masked
6. Compile BP2
7. In BP1, set Enum default from Opaque to Translucent
   • BP2 Enum value is still set to Masked
8. In BP1, Set Enum default from Translucent to Masked then to Additive

Result:
BP2 default value changes to match BP1 value if both start with the same value

Expected:
BP2 retains its own default setting independent of BP1 changes.
