爲什麼我的行在Google表格中追加兩次？

Question

我的腳本設置爲根據表單中輸入的項目類型將表單響應表中的行復制到不同的工作表中。出於某種原因，它已經開始在表單中添加兩行（使用完全相同的時間戳創建副本 - 請參見下面的截圖）。它以前沒有這樣做過，而且還只是偶然發生，但經常發生。我的腳本或谷歌表格本身有問題嗎？

function onFormSubmit() {//Distributes Form Submissions to the appropriate sheets depending on format and audience whenever new submission is made

當要刪除的行嘗試環路從底部，因爲當你刪除像行之間本作轉變排算，也許這將幫助你

for(i = dataA.length; i >= 1; i--){ 
    if (dataA[i][0].toString() == tsVal1.toString()){ 
    responseSheet.deleteRow(i + 1); 
    actSheet.deleteRow(actRow); 
    break; 
    }
