What sort of a bypass setup do you have? Perhaps there is a check valve that isn't operating properly (usually on the water heater output, I think). This would not apply to a three-valve bypass setup which has no check valves.
More broadly, I think it would have to be either a valve that is leaking when it should be shutting, or else operator error in setting one or more valves incorrectly. I've managed to get the settings wrong once or twice and had various rather confusing outcomes (confusing at least until I found my error).
