We present a re-analysis, with newly acquired atomic data, of the two detections of two highly ionized intervening OVII absorbers reported by Nicastro and collaborators (2018). We confirm both intervening Warm-Hot Intergalactic Medium OVII detections, and revise statistical significance and physical parameters of the absorber at $z=0.4339$ in light of its partial contamination by Galactic interstellar medium NII K$\alpha$ absorption.
