Drag and drop auto submitting after 1 answer

I am having an issue with Drag and Drop that I am unable to pinpoint- I have 2 drag and drop slides in Captivate 2019. Each one has 7 drag sources, and 3 drop. 

The intended action is for automatic submission upon all 7 drag sources being dropped to the correct locations. Currently, after dragging one source, after 3 seconds the presentation changes to the next slide.

I confirmed that I have "Continue playing the project"  unchecked, and cleared cache. 
This was working successfully, but now it's not so I must have done something, but I can't figure out what.
