Duplicated Matinee Actors cause compile errors with Controllers in Level Blueprint

Duplicating a Matinee Actor after having its controller placed in the Level Blueprint and then adding a controller into the Level Blueprint will cause a compile error on compile. *This error will seemingly disappear on a second compile.*

1. Open QAGame Editor
2. Create a New Matinee Actor
3. Open the Level Blueprint
4. Add a Controller for the New Matinee Actor
5. In the Viewport, Duplicate the Matinee Actor
6. In the Level Blueprint, Add a Controller for the Duplicated Matinee Actor
7. Compile

RESULTS: Compile Error - "Found more than one function with the same name None_Finished, second occurrence at ..."

EXPECTED: NO Compile errors
