In file \wp-content\plugins\woocommerce-wholesale-prices\includes\class-wwp-wholesale-prices.php add next code:

$price = $cart_item['data']->get_price();
if (class_exists('WOOCS')) {
    global $WOOCS;
    $currrent = $WOOCS->current_currency;
    if ($currrent != $WOOCS->default_currency) {
        $currencies = $WOOCS->get_currencies();
        $rate = $currencies[$currrent]['rate'];
        $price = $price / ($rate);
    }
}

$price = $cart_item['data']->get_price();

if (class_exists('WOOCS')) {

global $WOOCS;

$currrent = $WOOCS->current_currency;

if ($currrent != $WOOCS->default_currency) {

$currencies = $WOOCS->get_currencies();

$rate = $currencies[$currrent]['rate'];

$price = $price / ($rate);

}

Also add next code to the same file:

$price = $cart_item['data']->get_price();
if (class_exists('WOOCS')) {
    global $WOOCS;
    $currrent = $WOOCS->current_currency;
    if ($currrent != $WOOCS->default_currency) {
        $currencies = $WOOCS->get_currencies();
        $rate = $currencies[$currrent]['rate'];
        $price = $price / ($rate);
    }
}
