To prove that "Cementing the Quads' Legacy is 322: In production code order, there is a pattern of the quads' names showing up first in the "Starring" section after the theme song. And since that section would say "Starring Aidan Gallagher" in 302, 306, 310, 314, 318, and 322, and this episode said "Starring Aidan Gallagher", it confirms this episode is 322.

Besides, you can't trust just any website like The Futon Critic. People say The Futon Critic isn't reliable.
