Hi,
Sounds like you may have measured it incorrectly. Is the reservoir a pressurized bottle? If so, then this is the only place to add coolant. Also, be sure to mix the coolant before adding it to the vehicle, it will not mix together equally inside the system. I say make more of the mix and add while the car is running, turn the heat on, and wait for the level to drop after the thermostat opens. Then check your level and turn off the car, wait an hour and see where the level is again.
Let us know,
William
