Erratic trigger behavior, I can't find the fault.

Hi guys, I'm kinda at my wits end here. This is my problem:

I have 2 walls opposite of each other. The player can jump off these walls. There is a trigger collider attached to the player object. When the player jumps off one of the walls, this wall becomes "unjumpable" and the opposite becomes "jumpable".

I have this script attached to my player:

 public bool proccedLeft = false;
 public bool proccedRight = false;
 public bool procced = false;
 
 void OnTriggerExit2D (Collider2D other)
     {
         if(procced)
         {
             if(other.tag == "LeftWall")
             {
                 proccedLeft = true;
                 procced = false;
                 Debug.Log ("LeftProc:" + proccedLeft);
             }
             if(other.tag == "RightWall")
             {
                 proccedRight = true;
                 procced = false;
                 Debug.Log ("RightProc:" + proccedRight);
             }
         }
     
     }

Both walls share this script:

 public class WallControl : MonoBehaviour 
 {
 
     public GameObject oppositeWall;
     private Bouncer jumper;
        private Renderer myRend;
     void Start () 
     {
         myRend = renderer;
         myRend.renderer.material.color = Color.green;
         jumper = GameObject.FindGameObjectWithTag("Player").GetComponent<Bouncer>();
     }
 
     void FixedUpdate()
     {
         if(jumper.proccedLeft && tag == "LeftWall")
         {
             gameObject.layer = 13;
             oppositeWall.layer = 9;
             oppositeWall.renderer.material.color = Color.green;
             myRend.material.color = Color.red;
 
             print("LeftGone");
 
             jumper.proccedLeft = false;
             jumper.procced = false;
 
         }
         if(jumper.proccedRight && tag == "RightWall")
         {
             gameObject.layer = 13;
             oppositeWall.layer = 9;
             oppositeWall.renderer.material.color = Color.green;
             myRend.material.color = Color.red;
 
             print ("RightGone");
 
             jumper.proccedRight = false;
             jumper.procced = false;
         }
 
     }

Everything works, but sometimes a procc won't register. In other words the player jumps off a wall, but the wall stays available. This happens irregularly, I have playtested for 1 hour and have found no patterns. Now I know that in order for jump bool to be true, the trigger must return true when next to a wall. So the trigger works fine since I have no problems with other collisions.

I have tried many different solutions up until now. Tried sticking the wall logic in Update and even LateUpdate. Tried putting the trigger collider on a child object of the player. Tried separating the wall code and adding it to an empty game object. The result is the same. I even played around with the physics timestep.

I can't find a logical lapse in my code, so it seems to me on paper everything should be functional. The problem occurs not only at high speeds, but at low ones too.

Edit: This is my movement control code:

 void FixedUpdate ()
     {    
 
         float ms = Input.GetAxis ("Horizontal");
 
         // If the player is changing direction (ms has a different sign to velocity.x) or hasn't reached maxSpeed yet...
         if(ms * rigidbody2D.velocity.x < maxSpeed)
             // ... add a force to the player.
             rigidbody2D.AddForce(Vector2.right * ms * moveSpeed);
         
         // If the player's horizontal velocity is greater than the maxSpeed...
         if(Mathf.Abs(rigidbody2D.velocity.x) > maxSpeed)
             // ... set the player's velocity to the maxSpeed in the x axis.
             rigidbody2D.velocity = new Vector2(Mathf.Sign(rigidbody2D.velocity.x) * maxSpeed, rigidbody2D.velocity.y);
 
 
 
         if(jump)
         {    
 
             //If condition from update is met, jump and then reset the condition to false.
             rigidbody2D.AddForce (new Vector2 (gtfo,jumpForce) * comboJumps/2);
             jump = false;
 
 
             //Prevent the player from abusing the wall.
             if (player.position.x < startPosition.x)
             {
                 if (walled)
                     gtfo = repelForce * 20;
                 else gtfo = repelForce;
                 
 
             }
             if (player.position.x > startPosition.x)
             {
                 if (walled)
                     gtfo = repelForce * 20;
                 else gtfo = -repelForce;
 
             }
         }
 
     }
