Help with task reassignment

Hello! We have a task template we use in multiple projects, it has subtasks to complete different approvals and assets. We have one team member that when he enters a new asset approval (task) as each subtask is approved, it is reassigned to him. It happens in multiple projects, and I cannot find a rule to reassign the task once complete to him. Also, it only happens to him. Very odd, and wondering if that could be a setting somewhere.

HI @Kristen_Remick apologies for the late response. In that template there might be a variable assignee in the assignee part of the template?
