Why is my .appendRow from Array adding an extra row? - google-apps-script

Question

I pretty much have the Apps Script file working as intended. However, each time it is triggered, it also adds a second line where the sessionEmail is not captured and is blank.
function onEdit() {
var sessionEmail = Session.getActiveUser().getEmail();
var spreadsheetTimeZone = SpreadsheetApp.getActive().getSpreadsheetTimeZone();
var lastUpdatedString = Utilities.formatDate(new Date(), spreadsheetTimeZone, "MM/dd/yyyy' 'HH:mm:ss");
var s = SpreadsheetApp.getActiveSheet();
if (s.getName() == "Workload") { //checks that we're on the correct sheet
var r = s.getActiveCell();
if (r.getColumn() == 14) { //checks the column
var status = r.getValue();
var note = r.offset(0, -1);
var noteValue = note.getValue()
var delivery = r.offset(0, -5);
var deliveryValue = delivery.getValue()
}
// Validating fields are filled in
if (status == "Complete") {
var ui = SpreadsheetApp.getUi();
if (noteValue == '') { // if no note is entered, stop script with message box
var noStatus = ui.alert(
'Warning!',
'Please enter notation before choosing Complete.',
ui.ButtonSet.OK);
r.setValue('')
return;
}
// get destination range
var array = [lastUpdatedString, sessionEmail, deliveryValue, noteValue]
var ss = SpreadsheetApp.getActiveSpreadsheet();
var pasteSheet = ss.getSheetByName("Historical Notes Sheet");
pasteSheet.appendRow(array)
// clear response row
note.setValue('')
r.setValue('')
}
}
}
Image of what the results look like:
If any of you have any ideas on how to resolve this, and only append 1 line that has all the values, I would really appreciate it.
Thanks!
Update:
Logging the variable produces the following (expected) results, where the e-mail address appeared in the string.
Results still populating 2 rows:

Thanks for helping me troubleshoot.
I went into View>Executions, and noticed that the script was running twice each time at about 2 milliseconds apart. I think the function name onEdit() was acting like an On Edit trigger, and causing the script to run with another On Edit trigger that I had set up for it.
I tried removing the trigger, and leaving it with the onEdit()name, but that was causing it to not grab the sessionEmail. Changing the code to the below, and adding the trigger back causes the code to run as expected.
function appendLine() {
var sessionEmail = Session.getActiveUser().getEmail().toString();
var spreadsheetTimeZone = SpreadsheetApp.getActive().getSpreadsheetTimeZone();
var lastUpdatedString = Utilities.formatDate(new Date(), spreadsheetTimeZone, "MM/dd/yyyy' 'HH:mm:ss");
var s = SpreadsheetApp.getActiveSheet();
if (s.getName() == "Workload") { //checks that we're on the correct sheet
var r = s.getActiveCell();
if (r.getColumn() == 14) { //checks the column
var status = r.getValue();
var note = r.offset(0, -1);
var noteValue = note.getValue()
var delivery = r.offset(0, -5);
var deliveryValue = delivery.getValue().toString();
}
// Validating fields are filled in
if (status == "Complete") {
var ui = SpreadsheetApp.getUi();
if (noteValue == '') { // if no note is entered, stop script with message box
var noStatus = ui.alert(
'Warning!',
'Please enter notation before choosing Complete.',
ui.ButtonSet.OK);
r.setValue('')
return;
}
// get destination range
var array = [lastUpdatedString, sessionEmail, deliveryValue, noteValue]
var ss = SpreadsheetApp.getActiveSpreadsheet();
var pasteSheet = ss.getSheetByName("Historical Notes Sheet");
pasteSheet.appendRow(array)
// clear response row
note.setValue('')
r.setValue('')
}
}
}
Thanks again to everyone for your help!
