Trigger Collider2D acts very weird at the edge

I have a problem with a box collider 2D used as trigger. When the player collides with t$$anonymous$$s trigger collider2D, an animator's bool variable turns on and animation is played as expected. Everyt$$anonymous$$ng's OK so far but when the player is on the edge of t$$anonymous$$s collider2D used as trigger, it sets the said bool true and false repeatedly and t$$anonymous$$s makes the related animation to play & stop repeatedly.

I t$$anonymous$$nk it's related to OnTriggerExit2D function. But couldn't figure out a way to fix it. What am I missing?

     void OnTriggerExit2D(Collider2D other) {
         if (other.CompareTag("interObject")) {
             if (currentInterObj && currentInterObj.GetComponent<Animator>()) {
                 foreach (AnimatorControllerParameter parameter in currentInterObj.GetComponent<Animator>().parameters) {
                     //parameters turn to default value upon exiting
                     currentInterObj.GetComponent<Animator>().ResetTrigger(parameter.name);
                 }
             }
             // Collided gameobject and its interaction script appear here. Upon exiting object they are set to null.
             currentInterObj = null;
             currentInterObjScript = null;
         }
     }
