KEDA creates more jobs than the Redis list size

[Aegon95]

I am using KEDA v2.13. I have a scaled job which is connected to a Redis list

This is my scaled job configuration

apiVersion: keda.sh/v1alpha1
kind: ScaledJob
metadata:
  name: my-scaledjob
spec:
  jobTargetRef:
    parallelism: 1              
    completions: 1
    activeDeadlineSeconds: 86400
    backoffLimit: 1
    template:
      spec:
        volumes:
          - name: tmpdata
            persistentVolumeClaim:
              claimName: tmp
        imagePullSecrets:
          - name: {{.Values.global.image.PullSecret}}
        containers:
          - name: myapp
            image: myapp
            imagePullPolicy: {{.Values.global.image.PullPolicy}}
            workingDir: app
            command: [ "celery", "-A", "app", "worker", "--loglevel=info", "--pool=solo"  ,"--concurrency=1", "-O" , "fair", "--prefetch-multiplier=1", "-n", "%%h", "--max-tasks-per-child=1", "--without-gossip", "--without-mingle", "--without-heartbeat"]
            volumeMounts:
              - mountPath: "/tmp"
                name: tmpdata
  pollingInterval: 2             
  maxReplicaCount: 48         
  successfulJobsHistoryLimit: 0  
  failedJobsHistoryLimit: 2       
  scalingStrategy:
    strategy: "accurate"                       
  triggers:
    - type: redis
      metadata:
        address: redis:6379
        listName: celery
        listLength: "1"
        enableTLS: "false"
        activationListLength: "0"
        databaseIndex: "0"

If there are 9 messages in the redis list. I am expecting KEDA to create exactly 9 jobs, but KEDA creates 13 jobs or sometimes 11 jobs.

I did check Redis list( Redis is latest version), its not doing anything weird

These are the logs from KEDA operator

2024-02-20T09:33:33Z    INFO    scaleexecutor   Creating jobs   {"scaledJob.Name": "my-scaledjob", "scaledJob.Namespace": "my-test", "Number of jobs": 0}

2024-02-20T09:33:35Z    INFO    scaleexecutor   Creating jobs   {"scaledJob.Name": "my-scaledjob", "scaledJob.Namespace": "my-test", "Number of jobs": 4}

I don't understand what is Effective number of max jobs, that's always equals to the excess jobs/ delta. I don't know how to set it to 0.

Please help me in solving this issue
