The entanglement negativity $$\mathcal{E}$$(A : B) is a useful measure of quantum entanglement in bipartite mixed states. In random tensor networks (RTNs), which are related to fixed-area states, it was found in ref. [1] that the dominant saddles computing the even Rényi negativity $$\mathcal{E}$$(2k) generically break the ℤ2k replica symmetry. This calls into question previous calculations of holographic negativity using 2D CFT techniques that assumed ℤ2k replica symmetry and proposed that the negativity was related to the entanglement wedge cross section. In this paper, we resolve this issue by showing that in general holographic states, the saddles computing $$\mathcal{E}$$(2k) indeed break the ℤ2k replica symmetry.
