Water Dispenser leaking

Kenmore side by side refrigerator. Ice maker works fine. Water dispenser works but when I release the water actuator it doesn’t shut off the water right away so a little leaks into the tray each time I use it. Also when the ice maker calls for water for some reason water starts running out of the water dispenser (50% pressure about). I checked the pressure fitting at bottom of door and it’s fine. I took apart the dispenser panel and don’t see anything that work control this (ie close and shut the water tube at the water dispenser. What do you think is wrong and what part do I need to replace. Thanks
