I've got a scheduled script that runs daily at midnight, It creates a task for each customer result of a search. I'm setting the 'sendemail' field to false, and when I look at the task record. It does set the checkbox to unchecked. However the task is still sending the email to the sales rep. Has anyone run into this issue? Is there something I'm missing?  Here is my code of creating a task:

                var taskRec = record.create({                      type: record.Type.TASK,                      isDynamic: true,                      defaultValues: {                          customform: 72                      }                  });                    taskRec.setValue({                      fieldId: 'title',                      value: 'SO Follow Up Task'                  });                    taskRec.setValue({                      fieldId: 'company',                      value: customerId                  });                    taskRec.setValue({                      fieldId: 'sendemail',                      value: false                  });                    taskRec.setValue({                      fieldId: 'status',                      value: 'NOTSTART'                  });                    taskRec.setValue({                      fieldId: 'custevent12',                      value: 22                  });                    var lookupFields = search.lookupFields({                      type : 'customer',                      id : customerId,                      columns : ['salesrep', 'email', 'phone']                  });                    var salesRep = lookupFields.salesrep[0].value;                  var email = lookupFields.email;                  var phone = lookupFields.phone;                    taskRec.setValue({                      fieldId: 'assigned',                      value: salesRep                  });                  taskRec.setValue({                      fieldId: 'custevent8',                      value: email                  });                  taskRec.setValue({                      fieldId: 'custevent7',                      value: phone                  });                    taskRec.save();
