A Controller:WaterCoil is only necessary for water coils that are connected to an AirLoopHVAC directly. Coils inside of reheat terminals or unitary equipment objects do not need them, because in these situations the coils are controlled by the object that contains them.
Based on your screenshots, it doesn't look like these coils are connected to an AirLoopHVAC directly. If they were, there would be little circles on the coil icon.
In the screenshot below, the top coil is connected to an AirLoopHVAC directly, while the bottom coil is inside of an AirTerminal:SingleZone:Reheat. The top coil has a Controller:WaterCoil but the bottom coil doesn't.
