Already got the job but its still open on Indeed?

I’ve already started the job and I’ve been working for almost a month, and its been going great! I still get Indeed emails so I went on it randomly one day and noticed the job I currently have is still open and it says that the employer actively reviewed candidates recently. I overthink a lot so I’m scared this could mean they’re still looking for another person to replace me? The job only had one opening.
