Unable to turn off "Water Detected" in base station

Just set up the two water sensors today and did a test to make sure it can detect water.Used default setting which included 10 minute alert.Got the notification, but after 10 minutes the base station kept on repeating "Water Detected" with blue lights on. From dash board I am supposed to see some event that allows me to Dismiss, but I do not see any.In History Event it says water detected followed by water cleared.I looked all over in the water sensor and base station and nothing allows me to turn off the event.I also went back to sensor configuration and turned off the 10 minute alert.
