UPROPERTY variables show in all components of Blueprint instead of just the Actor they belong to

Variables declared with UPROPERTY( ) are shown in all components in Blueprint components tab.

1. Create new empty c++ project
2. Launch project and add new c++ class extending Character
3. Add following code to new Character class:

      UPROPERTY( BlueprintReadWrite, EditDefaultsOnly, Category = "Testing|SecondTesting" )
      uint8 MyInt;	
   

4. Save and compile.
5. Right-click on class in UE4 and make Blueprint class from Character class
6. In the new Blueprint class, switch between the components.

RESULT:

"MyInt" is visible from all components in the Character class.

EXPECTED:

Only the Character class can see "MyInt".
