How to remove the selected value in the DropSownList on the next line. With the addition of MultipleInput?

Question

Yii

The task is to remove the selected value in the next line of the DropDownList.
There is already a script that does this, but it also removes the very first value. That is, there are 2 values
​​First
Second
Third
When the page is loaded, the first one is already removed. (this needs to be fixed somehow)
I choose the second and only the third remains in the next line.

$('.multiple-input').on('afterAddRow', function(e, row) {
        console.log('calls on after add row event', $(row));
            var selected = [];
            $('.multiple-select').each(function(index, ele) {
                var val = $(ele).val();
                if (val) {
                    selected.push(val);
                }
            })
            
            $(row).find('.multiple-select').first().find('option').each(function(i, ele) {
                if (selected.indexOf($(ele).attr('value')) !== -1) {
                    $(ele).remove();
                }
            })
        })
