check box showed up in reports

Random check boxes appeared for different report applications.  There doesn't seem to be a pattern in where they show up or for who.  For example, the home page for an app called "Task", it shows up for me but not another employee.  However, it does show up in other application reports for both me and the employee..  The check box is located next to the view and edit icon.  As far as I know, nothing has changed.  I tried going to the report itself but don't see anything for a check box that isn't accounted for.  If I could attach an image I would.  Any help would be appreciated.
