[Plugin: WooCommerce – excelling eCommerce] wp-admin-bar doesn´t work properly after last updatin

custom wp-admin-bar doesn’t work properly, I’m using a custom theme and in this theme, i chose to always show the wp-admin-bar with some options to make the navigation more simply, but after the last update of the woocommerce plugin, the wp-admin-bar continues appearing but on the footer of the page and with no css just appear as a link, how can i fix it?

thanks
