For the defining equation of the arrangements \(\mathcal{CL}_{7}\) there is a missing variable \(z\) in the last two factors. One should have:

$$\begin{aligned} & \mathcal{CL}_{7}: (x^2+y^2-z^2)\cdot(x^2+y^2-4z^2)\cdot(x-z) \\ &\quad \bigg(y + \frac{\sqrt{3}}{3}x + \frac{2\sqrt{3}}{3}z\bigg)\cdot\bigg(y - \frac{\sqrt{3}}{3}x - \frac{2\sqrt{3}}{3}z\bigg)=0. \end{aligned} $$
