[PS5] Eldritch altar map boss mode error?

I gained a map boss altar during a Sepulchre map. Gladiator- main skill splitting steel, did used culling strike on my leap slam but item drop vanished(never dropped). Maybe due to phase shifting between 2forms?(the altar buffs only one form?) Other items dropped fine.

Altar stat.
189% increased armour
161% increased evasion rating
Nearby enemies are hindered, with40% reduced movement speed
Final boss drops 3 additional lesser eldritch embers
Final boss drops 4 additional Vaal ords

3.25.1 pre-view patch fixes it.

Fixed a bug where the Sepulchre Map Boss, Doedre the Defiler, would fail to drop guaranteed rewards after being killed in her second form.
