Lock Attack settings are not reflected

"Lock Attack: When a player enters a locked monument, do we lock their attacking abilities?": false,
Even with the above setting, if a player enters a monument locked by another person and attacks NPCs, the damage does not register.
Once the lock is released by the other person, damage is applied normally.
We confirmed this behavior at the harbor, but it may also occur at other monuments.
We kindly ask for your confirmation.
