I think the subtracted error estimate e_φ(x_t, t, ∅) should be written as e_φ(x_t; ∅, t) to match the other quantities in the expression.

Can you explain why e_φ(x_t; y, t) is added twice in the classifier free guidance?

Hi, thanks for pointing that out. It is a typo, and the second term should be $\omega \epsilon_\phi(x_t;y, t)$
