Drag and drop error on output for adobe animate CC

Hai,
I have try do on adobe animate CC the drag and drop activities for my project. When I test scene, all look good which when I drag the object to the correct box, the response box will appear "correct" while when I drag the object to the wrong box, the response box will appear "wrong". It happen like what I insert in action script. But the output will show the error (picture). How can I solve this output error?
Does the output error effect the animate project? Since when I test scene or movie, its works well.
