Direct repeater item to dynamic page

Well, damn. Both of my datasets are by default “dataset1” and as I’m just playing with the formatting, moving around buttons, it’s making a mess of things. The “next” button is taking it to the other dataset and dynamic page.
Do you have any thoughts on this? I just keep undoing my changes and trying again.
Googling this topic it says you can’t rename a dataset :frowning:
