Each grid is set to 32, and your speed is 120, that means you have .325 seconds to show the animation before it resets. With each frame set to 10, that will give you .4 seconds of animation to show for each cell... not enough time.
You can either change your grid settings, and animation settings.... or, not use tags and set up your own with events:
+ Hero: is moving
-> Hero: Set animation to "archerwalk"
+ System: Else
-> Hero: Set animation to "archerstand"
