Else statement still running when if statement is true with google script

I have a function that has a name with a set of data and this name is compared to a list of names. If that name is already in the list of names, the data associated with the name replaces the old data. If the name is a name not in the list of names it adds the name and the associated info to the bottom of the list.

For some reason when I run the code with a name already in the list, the original data is replaced and the name and data are added to the bottom of the list. I want to avoid repeating people while also adding new individuals.

  var app = SpreadsheetApp;
  var activeSheet = app.getActiveSpreadsheet();
  var lookup = app.getActiveSpreadsheet().getSheetByName("Lookup");
  var issued = app.getActiveSpreadsheet().getSheetByName("Issued");
  var name1 = lookup.getRange(12,3).getValue();
  var info = lookup.getRange(16,3,1,12).getValues();
  
for (var j=1;j<105;j++){
    var issuedOfficers = issued.getRange(j,11).getValue();
//if the officers name is already recorded in issued the system will replace the current data with updated data
    if (issuedOfficers === name1){
      issued.getRange(j,1,1,12).setValues(info);
    } else {
      var lastrow = issued.getLastRow();
      issued.getRange(lastrow+1,1,1,12).setValues(info);
      break;
    }
}
}```
