1. Evaporator is a flooded flake ice drum

if your system is a flooded system, I can't see any device for an oil return from it.
So the oil missing in the oil separator is probably the oil drained from the ice machine + the oil mixed with refrigerant in the surge drum.

Sorry you are right. The system is not flooded. It is direct expansion with throttling valve.
