Animation gets stuck at the end in Unity Animator

I am not good at animating in 3D so I have a slight problem. I am making a swinging animation with a bat. Every animation works perfectly fine, but what's the problem here is that when from idle animation goes to swing animation it gets stuck, I have to click few times to return to idle state.


This is how animation looks like. Here is where it gets stuck:

At the end of "swing2" animation it stops, and I have to click 2 or 3 times to get through transition back to "idlestate". Here I am showing you the inspector of these two transitions:


I am trying to solve this problem for some time now and still don't get it why it's happening.
Here you can check out the code for this. This script is specifically for melee weapons but I think it can apply to other items as well. Everything in the code works except this animator part.

Code (CSharp):

1. using UnityEngine;
2.  
3. public class melee : MonoBehaviour
4. {
5.     public float dmg;
6.     public float range;
7.  
8.     private Animator anim;
9.     private bool attacking = false;
10.  
11.     public Camera cam;
12.  
13.     void Start(){
14.         anim = gameObject.GetComponent<Animator>();
15.     }
16.  
17.  
18.  
19.     void FixedUpdate(){
20.         AnimatorStateInfo info = anim.GetCurrentAnimatorStateInfo(0);
21.         if(Input.GetButtonDown("Fire1")){
22.             Attack();
23.          
24.         }else if(Input.GetButtonUp("Fire1")){
25.             anim.SetBool("attacking", false);
26.         }
27.  
28.     }
29.  
30.     void Attack(){
31.         RaycastHit hit;
32.         if (Physics.Raycast(cam.transform.position, cam.transform.forward, out hit, range)){
33.             Debug.Log(hit.transform.name);
34.  
35.             enemyHealth enemy = hit.transform.GetComponent<enemyHealth>();
36.          
37.             if(enemy != null){
38.                 enemy.TakeDmg(dmg);
39.             }
40.  
41.         }
42.  
43.  
44.         anim.SetBool("attacking", true);
45.     }
46. }
47.  

Also how do you add a blocker so that you cant swing or attack again until animation finishes?

 

To avoid input loss, I would move checking user input to

Update

as it runs every frame, instead of

FixedUpdate

which doesn't.
And i guess there is no need to check for

GetButtonUp

in

else

statement.
