The loop does not repeat properly with a specified number of repetitions in AHK

I have a few lines of code like this. Each iteration will add 1 record to the list. i have tried setting the number of iterations to 100 but sometimes record list is just 97 or less than 100. i can't find the cause. what can I do to fix it?

    loop, % loopNum      {          ie.Document.QuerySelector("input[id='textIndex']").value := A_index          ie.Document.QuerySelector("input[value='Add']").Click()          IE.WaitComplete(ie)  // check if IExplorer is complete status then sleep 100s      }
