Price format in a category from variable products, how to decide?

Question

WordPress

Hello!
Please tell me what is wrong.
Here the filter displays the minimum price of the variation in the product category.

add_filter('woocommerce_variable_price_html', 'custom_variation_price', 10, 2);

function custom_variation_price( $price, $product ) {
 $price = '';
 $price .= woocommerce_price($product->get_price());
 return $price;
}

But it doesn't display the discount if this variation has one.
And here is the code that displays the minimum price and the discount if there is one, but somehow strange, it takes the price from the ceiling.

add_filter( 'woocommerce_variable_price_html', 'custom_min_max_variable_price_html', 10, 2 );
function custom_min_max_variable_price_html( $price, $product ) {
    $prices = $product->get_variation_prices( true );
    $min_price = current( $prices['price'] );
    $max_price = end( $prices['price'] );

    $min_keys = current(array_keys( $prices['price'] ));
    $min_price_regular = $prices['regular_price'][$min_keys];
    $min_price_html = wc_price( $min_price ) . $product->get_price_suffix();

    if( $min_price_regular != $min_price ){ // When min price is on sale (Can be removed)
        $min_price_regular_html = '<del>' . wc_price( $min_price_regular ) . $product->get_price_suffix() . '</del>';
        $min_price_html = $min_price_regular_html .'<ins>' . $min_price_html . '</ins>';
    }
    $price = sprintf( __( '%1$s', 'woocommerce' ), $min_price_html );

    return $price;
}

What comes out, the first code prints the minimum price of the variation 271 - right! (old price 362)
The second code displays the minimum price of the same variation 288 - how is that? (old price 360)
Please help me blind...

And so?

add_filter('woocommerce_variable_price_html', 'dco_woocommerce_variable_price_html');

function dco_woocommerce_variable_price_html($price) {
    $array = explode(' – ', $price);
    return '<span class="price-from">от</span> ' . $array[0];
}
