Practice Section

I’m having an issue with the new practice section on the today tab of the site. If I leave off at the start of a lesson, it only gives me the option to practice that current lesson, which I haven’t yet learned. I really would like to go back to practice the section I’d just completed.
I can’t find any way to click through in order to do that. I’m sorry if my question isn’t clear - anyone else having this issue?

Thanks in advance,
