Using a water pump with cycle and soak

I have a submersible pump that runs off a relay triggered by the Rachio when starting a zone. I was playing around with the cycle and soak settings on a test schedule and went out to witness that it was applying water then stopping to soak. Unfortunately it never cut power to the relay so the pump just kept running then entire scheduled time even though I had cycle and soak intervals at 1 minute each with a total watering schedule of 10 minutes. Do I have something setup improperly?
