Span columns with two separate paragraphs above each other?

I'm taking a course on this software but I'm stuck on making a recipe page using spanned columns. The sample given looks like this

And despite following the intructions given by the textbook / instructor video it just isn't stacking this way? We aren't supposed to make an additional text box or breaks for this - it's all one Placed text that we need to span the two colums, but the ingredients list needs to automatically stack above the next paragraph for the preparation instructions. According to the video we were given you simply need to highlight "Preparation" and select it to span all columns, then the ingredients list just stacks itself on top on its own.

Mine isn't doing that and I'm unsure why. Any ideas?
