WooCommerce Multi Currency

I’m using [woo_multi_currency_layout4] shortcode in my header for mobile responsive screens and the problem is that the dropdown arrow is currently overlapping the country flag. I would like to hide the arrow and only display the country flag.

Another bug I found in this shortcode is that by clicking the flag again is does not collapse the currencies (on smartphones). So after tapping to expand the currencies, the only way to hide the dropdown again is to click somewhere else on the screen.

Thanks for listening
