Multiple Drag and Drop into Multiple Targets with only 1 correct answer - getting error

The students are going to be building a diagram in a multiple drag and drop to multiple targets interaction. It's a graded Pick 1 free form slide. The interaction is not registering that the question has been completed when the custom submit button is clicked. I've attached a file with rough sketches of the slide that works and the slide that does not. 

This is the message I'm getting when I drop objects in and click the Submit button:

"Invalid Answer: You must complete the question before submitting."

Can you help me figure out why the one labeled Example works, but the other one does not.

Thank you, 

Roseanne

Hi Roseanne and welcome to E-Learning Heroes :)

Thanks for contacting us and sharing what you are experiencing with your project.

I was able to take a look at the file you shared and identify the culprit.

Take a look at my quick Peek 360 video so that you can see how to correct this issue.
