The problem is that WPF animation locks the property value even after the animation is completed. To prevent that you need to change the animation's FillBehavior from HoldEnd to Stop.

You can also try any of the steps described here: https://msdn.microsoft.com/en-us/library....110).aspx

Thanks Andrej

The .Stop did not work, but removing the animation from the property on completion does!
