GUID property is not fully generated for a component added to a Blueprint in the Editor

If a component contains a GUID property, and that component is added to a Blueprint in the Editor, that property is not fully generated for instances of the Blueprint. Only the first part of the GUID is generated, the rest of it remains set to whatever the default value is.

This only occurs if the component is added to a Blueprint in the Editor. If a component containing a GUID property is added through code to a code class, the GUID is fully generated.

REGRESSION:
No. This behavior occurs in 4.15 as well.

1. Create a new Blank Blueprint project.
2. Create a new ActorComponent Blueprint.
3. Add a new variable to the component of type GUID and set it to be Instance Editable.
4. Create a new Actor Blueprint.
5. Add the previously created ActorComponent Blueprint to the new Actor Blueprint.
6. Place an instance of the new Actor Blueprint into the level.
7. Make sure the instance in the level is selected.
8. Select the ActorComponent in the Details panel.
9. Locate the GUID property.
10. Click the down-arrow to the right of the field and select the Generate option.

RESULT:
The first part of the GUID is updated, but all of the other parts of the GUID value remain the same as they were previously.

EXPECTED:
Every part of the GUID is updated with new generated values.
