Archive rows going to very bottom of sheet. Not right under last row

Question

enter image description hereI have the below code working in apps script. It does what it is supposed to as in auto archiving and deleting the rows when a checkbox is selected. The only hiccup is it is archiving the rows to the very bottom of the archive sheet, not right under the last archived row. It skips a lot of blank rows for some reason.

function onEdit(e) {
  const sh = e.range.getSheet();
  if (sh.getName() == "ACTIVITY REPORT" && e.range.columnStart == 1 && e.value == "TRUE") {
    var tsh = e.source.getSheetByName("Archive");
    var target = tsh.getRange(tsh.getLastRow() + 1, 1);
    sh.getRange(e.range.rowStart, 1, 1, sh.getLastColumn()).moveTo(target);
  }
  if (sh.getName() == 'Archive' && e.range.rowStart > 1 && e.range.columnStart == 11 
&& (e.value == 'NP CND A ACCEPTED' || e.value == 'NP BACKGROUND')) {
    SpreadsheetApp.flush();
    e.range.offset(0, 16).setValue(new Date());
  }
  if (sh.getName() == 'Archive' && e.range.rowStart > 1 && e.range.columnStart == 11) 
    {
    let ops = ['NP CND A ACCEPTED', 'NP BACKGROUND', 'HIRED INTERN-SP', 'HIRED SDR- 
  SP', 'HIRED', 'HIRED INTERN', 'HIRED SDR', 'HIRED SDR', 'NP AS', 'NP LDR', 'NP CND A 
  AR', 'NP CND A OFFER', 'NO SHOW', 'NP ORL', 'NP CND A Zoom Int', 'NP CND A 1 FL'];
    if (~ops.indexOf(e.value)) {
      e.range.offset(0, 14).setValue(new Date());
    }
  }
  }
