Sum All Odd Fibonacci Numbers, not able to pass last test condition

Hi I was able to pass the test conditions set by the challenge except fib(75025), not sure why. Please find below code to the issue. Thank you

function sumFibs(num) {
  
  var num_arr = [1,1];
  var i = 1;
  var result = 0;
  var fib = 0;
  var j = 0;
  
  while ( result < num ) {
    
    result = num_arr[i] + num_arr[i-1];
    num_arr.push(result);
    i++;
  } //with this loop, unsure why the last element is added
    //for instance with num being 4,
    // you get [1,1,2,3,5], why "5"? shouldn't the loop stop and terminate?
  
  
  num_arr.pop(); //pop the last element
  
  while ( j < num_arr.length ) {
    
    if ( num_arr[j] % 2 != 0) {
      
      fib = fib+num_arr[j];
    }
    
    j++;
  }
  return fib;
}

The challenge instructions state:

Given a positive integer num, return the sum of all odd Fibonacci numbers that are less than or equal to num

Your solution returns the sum of all odd Fibonacci numbers that are less than num.
