Child actor component removed when changing the class of a child actor component

Child actor component removed when changing the class of a child actor component. Only the default class for the child actor component is used. If the user attempts to change the class the child actor component is removed.

1. Download the attached project
2. Open the project
3. Play in Editor
4. Press the '1' key to toggle between Child actor 'B' and Child actor 'C'
5. Notice that nothing prints when changing the child actor class and that the number of child actor components goes down to zero

Expected: The number of child actor components would remain the same and the Class for the child actor component would be toggled between 'B' and 'C'.
Result: Only the default class for the child actor component is used. If the user attempts to change the class the child actor component is removed.
