Animation resume after task

(NEW) I have a zombie AI which walks around randomly, the animation works here. If it spots the player, it will do a scream animation (played through a task in the behavior tree) before chasing the player. However when the scream is finished the zombie does not play the walking blendspace animation. If i remove the scream from the behavior tree the animation works perfectly.

This Behavior Tree does all of the Movement (not the moving animation)

This is the Screaming Task. The WAIT after the scream task on the behavior tree is the length of the animation (I do not know how stop the walking animation outside of this).

Any help would be appreciated.
