My particle system is not working and I unsure why

I am trying to have a mini-explosion in my game so I am using a mini-explosion, however it doesn't work, here is a video showing what is happening: https://youtu.be/S_U4AN-RFFQ. Basically it randomly triggers the effect and I am unsure why this happens. Here is the settings for the particle system:

Edit: Here is an image of the emmision module

Relevant code:

public class Alk : MonoBehaviour
{
    public ParticleSystem particle;
}

Alk alk;

    private void Start()
    {
        if (gameObject.GetComponent<Alk>() != null)
        {
            alk = gameObject.GetComponent<Alk>();
        }
    }

    {
        switch (state)
        {
            case State.Chase:
                ChasePlayer(playerPos, Gself, anim, agent, AttackRange, inRange, inView, HasSeenPLayer);
                break;
            case State.Attack:
                AttackPlayer(playerPos, anim, agent, Gself, MultiAttack, inRange, inView, AttackRange, isBlocking, HasSeenPLayer);
                break;
            case State.Idle:
                IdlePlayer(playerPos, anim, agent, Gself, inRange, inView, HasSeenPLayer);
                break;
            case State.Wander:
                WanderPlayer(playerPos, anim, agent, Gself, HasSeenPLayer);

        if (distDif >= AttackRange)
        {
            agent.SetDestination(playerPos.transform.position);

        }
        
        if (!PlayerPos.FindPlayerPos(AttackRange, playerPos.transform, inView, self, HasSeenPLayer))
        {
            anim.SetBool("Attack", false);

        if (random == 0) random = Random.Range(1, 5);

        if (random == 1)
        {
            StartCoroutine(PlayAnim(anim, "Attack"));
            random = 0;

        }

        if (random == 2)
        {

            random = 0;
            return;
        }

        if (random == 3)
        {            
            if (alk != null)
            {

            StartCoroutine(AlkAnim(anim, "Attack3"));

            //StartCoroutine(PlayAnim(anim, "Attack"));
            random = 0;
            return;
        }

        if (random == 4)
        {
            BlockPlayer(playerPos, anim, agent, inRange, inView, self);
            random = 0;
            return;
        }

        StartCoroutine(PlayAnim(anim, "Attack"));
        random = 0;
        return;

    }

    IEnumerator AlkAnim(Animator anim, string booleanName)
    {
        anim.SetBool(booleanName, true);
        yield return new WaitForSeconds(anim.GetCurrentAnimatorStateInfo(0).length + anim.GetCurrentAnimatorStateInfo(0).normalizedTime);
        anim.SetBool(booleanName, false);
        if (alk != null)
        {
            alk.particle.Stop();
            alk.particle.gameObject.SetActive(false);
            random = 0;
        }
    }

    public static bool HasParameter(string paramName, Animator animator) // checks to see if it has that parmameter
    {
        foreach (AnimatorControllerParameter param in animator.parameters)
        {
            if (param.name == paramName)
                return true;
        }
        return false;
    }

    IEnumerator PlayAnim(Animator anim, string booleanName) //sets chosen anim bool true, waits length of the anim, sets bool false
    {
        anim.SetBool(booleanName, true);
        yield return new WaitForSeconds(anim.GetCurrentAnimatorStateInfo(0).length + anim.GetCurrentAnimatorStateInfo(0).normalizedTime);
        anim.SetBool(booleanName, false);        
    }

THis is how it gets called: (In other script)

void Start()
    {      

        StartCoroutine(GetGood());
    }

    IEnumerator GetGood()
    {        
        TtF.ChoseChasingWhatStateToAttackPlayer(agent, Player_pos.player, self, anim, MultiAttack, inRange, inView, AttackRange, isBlocking, hasSeenPlayer);
        
        yield return new WaitForSeconds(0.5f);
        StartCoroutine(GetGood());
    }
