Copying values of an array created through C++ does not copy all values

Copying values of an array created through C++ does not copy all values, only the first value is copied over. This is different than an array that is created in blueprints when those are copied they print out all the values of the array. This issue is not a regression.

Versions Tested:
4.15.3 - CL: 3450819
4.16.3 - CL: 3561208
4.17.1 - CL: 3586342
Issue occurs in all versions tested

1. Create a new C++ Project
2. Create C++ MyActor based on AActor
3. In MyActor.h set up the blueprint like the image provided
4. Build the project
5. Create a Blueprint based on MyActor
6. Open Blueprint and try to copy whole MyArray to clipboard, by right-clicking on it and selecting Copy
7. Paste clipboard into some text editor or notepad
   Result: only the first value is printed
   Expected: The whole array is printed
