delete a specific array element when date expired of it

I have user levels for access content. I made a start date and end date input for each other. Each level has its own history. Whichever level date exceeds today’s date, it will be removed from user levels array, but all of them are removed in my function. How can I do that?

add_action( 'show_user_profile', 'crf_show_extra_profile_fields' );
add_action( 'edit_user_profile', 'crf_show_extra_profile_fields' );

function crf_show_extra_profile_fields( $user ) {
  $choices = [
    '+15 minutes'  => '2 Hafta',
    '+9 months' => '9 Ay',
    '+12 months' => '12 Ay',
    '+2 minutes' => 'Uzat',
];
$rua_user = rua_get_user( $user->ID );
$user_levels = $rua_user->get_level_ids();
$current_date = date("d/m/y H:i:s");

  foreach ( $user_levels as $user_level ) {

    $start_time_meta = 'start-time-'.$user_level;
    $start_time = get_the_author_meta( $start_time_meta, $user->ID);

    $end_time_meta = 'end-time-'.$user_level;
    $end_time = get_the_author_meta( $end_time_meta, $user->ID);

    $effectiveDate = strtotime($end_time, strtotime($start_time));
    $time = date("d/m/y H:i:s", $effectiveDate);

    ob_start();

    if ($current_date > $time) {
        $f = "EXPIRED";
    }

    echo esc_html( get_the_title( $user_level ) ) . ' -> ';
    ?>
    <input type="datetime-local" id="start-time-<?php echo esc_attr( $user_level ); ?>" name="start-time-<?php echo esc_attr( $user_level ); ?>" value="<?php echo esc_attr( $start_time ); ?>"> -

the cronjob function is executing by a cron plugin
