Size of boxes for drag and drop - won't size right

I am using this template. I edited the sentences for my project. Storyline 360: Drag-and-Drop Matching Labels - Downloads - E-Learning Heroes (articulate.com)

I have tried everything to make the boxes be a decent size when dropped so the text isnt looking too big and so that the words look like it is part of the sentence, but it is still not working. 

Any suggestions?
