Drag and Drop Stack Top to Bottom

I have a project that I'm working on where I need to make some adjustments to a Storyline project that was created a few years ago in Storyline 2.  I didn't create this project, but I've been tasked with editing it.

There are 2 drag and drop slides, and the first one works as intended.  When the answers are dropped in the right target, they stack from the top to bottom.  I don't think this is a Storyline default option, and I suspect it was built with some kind of workaround.

The second slide needs to function like the first, but it didn't have the workaround built in.  I've spent a few hours trying to figure out how to make it act the same, but none of the built in options (tile, random, free, etc.) seem to accomplish this.

I am wondering what I need to do in order to make the second slide function like the first?  I have attached a file with just these 2 slides for reference.

Thanks!
