How to reset (and clear) a self-checking activity

I’m very grateful to By Andy Schwen and Cathy McDonagh for creating an original activity on solving equations. I’m borrowing a screen from it for my students (Reset question • Activity Builder by Desmos)

When it creates a new problem, the graph on the left resets, and the equation that goes with it. But the previous entries are still in the table, and in the line-by-line checking code above it. Is there a way to modify the CL so that with a new equation, you actually get a blank slate?
