The paper that I'm seeing only has 4 figures.
In any case, the need for impurities would not itself surprise. Having controlled amounts of impurities is called "doping", it is well-known from studying semiconductors and other high temperature superconductors that the amount of doping can have a huge impact on a substance's properties.
See https://physicsworld.com/a/the-ups-and-downs-of-doping/ https://physicsworld.com/a/the-ups-and-downs-of-doping/ for verification of this point.
