exactly what i was thinking...
or...did you route your coolant overflow to your supercooler instead of leaving it hooked up to your radiator.
There is enough volume in the supercooler to not need more overflow than is in the hoses, but the radiator volume probably lends itself to needing the stock overflow tank to help circulate more... just a thought.
