Woocommerce currency missing

I seem to have some problems with my currency with Woocommerce, on my shop i need to have “Kr” instead of “DKK” so i added the following at the end of Functions.php

add_filter( ‘woocommerce_currencies’, ‘add_my_currency’ );

function add_my_currency( $currencies ) {
$currencies[‘Kr’] = __( ‘Currency name’, ‘woocommerce’ );
return $currencies;
}

add_filter(‘woocommerce_currency_symbol’, ‘add_my_currency_symbol’, 10, 2);

function add_my_currency_symbol( $currency_symbol, $currency ) {
switch( $currency ) {
case ‘Kr’: $currency_symbol = ‘Kr’; break;
}
return $currency_symbol;
}

But now afterwards as i removed the line again, now i don’t have any currency at all on the shop.

You can see it on below link:

Click on any product and you will see what i mean.
