Strange script in ReplicatedFirst giving me error?

So I was playing my game and when I left I got an error. I did some digging and found this script in replicated first. I don't know what it is, but does it have to do with the Kohl's Admin Infinite I put in my game? The local script is too long to include, but here is a snippet:

The error I get is

14:53:14.722 - 
14:53:14.723 -  is locked, current parent: NULL, new parent ReplicatedFirst

The script has no name. I only started having this after inserting Kohl's Admin Infinite. The real version, by Scripth, I checked.
