delay in displaying options when toggling visibility in a dropdown menu

When you first click on the select, it displays incorrectly

But when you click on it a second time, it displays correctly

$(document).on("click", "#edit_afpDetalle_mes", function () {
        updateSelectsMonth('#edit_tabla_afp_detalle');
    });
 
    $(document).on("click", "#btnEliminarFilaEdit", function () {
        deleteRow(this);
    });
function updateSelectsMonth(input_id) {
    // Get all selected months in existing rows
    var selectedMonths = [];
    document.querySelectorAll(input_id + ' tbody select').forEach(function (select) {
        if (select.value !== '') {
            selectedMonths.push(select.value);
        }
    });
 
    // Update each select in the table
    document.querySelectorAll(input_id).forEach(function (select) {
        select.querySelectorAll('option').forEach(function (option) {
            // If the option is selected in another select, hide it
            if (selectedMonths.includes(option.value) && option.value !== select.value) {
                option.style.display = 'none';
            } else {
                option.style.display = 'block';
            }
        });
    });
}

The select should display options like in the second image, but there is a delay where initially all options are shown and then quickly hidden except for the selected ones.

If you find that there is a delay in loading, it may be because the options are only loaded when the user clicks to see them. This lag can become more noticeable during application load times or when there is transit time involved.

To provide a smoother experience with these options, consider loading the data when the document is ready. Additionally, you can set up handlers for updates when any of the options are selected.
