Task is getting assigned to two users when I am telling it to assign only to one user

I have this issue where the task is getting assigned to two users when I am actually configuring it to assign task to one user alone. I created a process variable called assignee of type User and this is the logic:

pv!reopenTaskFlag = true(),

In the case where I am having the issue, pv!reopenTaskFlag=true() so it should be returning pv!IA_Task.requestedBy which is of type User. When I monitor the instance, pv!assignee has the correct value (just one user). But for some reason the task is also getting assigned to the initiator... Below is a screenshot of the user input task assignment node. Any idea what the problem could be?
