How to set up plugin for Woocommerce on Wordpress?

Question

Electronic commerce

There is such a problem with setting up a plugin for Woocommerce that displays different currencies. Installed WooCommerce Currency Switcher, turned it on and got a couple of problems.
So. It turns out that the main currency there is the US dollar.
This is how the basket for the dollar looks like

. And in the end, everything is correctly calculated, the delivery is also 1.5 bucks

. And now we just switch to EURO. The page has been updated and now the cart is correct.

But now the delivery has suddenly grown many times, although it costs $ 1.5

The same thing, if, for example, we switch to Ukr. hryvnia or ruble
AND delivery

I understand that this is a plugin bug. Here I found a crutch, which should help with something, but it did not help anything.

add_action('woocommerce_before_calculate_totals', 'fix_currency_conversion');
function fix_currency_conversion($cart_object){
            global $WOOCS;
            $cur_currency = $WOOCS->current_currency;
            $currencies = $WOOCS->get_currencies();
            $conversion_rate = $currencies[$WOOCS->current_currency]['rate'];
            if($cur_currency == 'USD'){
                foreach ( $cart_object->cart_contents as $cart_item_key => $cart_item ) {
                    $cart_item['data']->price = $cart_item['data']->price / $conversion_rate;
                }
            }
}

Can you tell me other adequate plugins or how to insert crutches here at least.
In short, who can
