Login/Register link in header

Hi,

As the topic title suggest, I am having an issue with getting the login/register link in the header to appear properly. The login/register link appears but the alignment is stacked vertically instead of horizontally. Attached is a screenshot. Here is the code I used in functions.php

add_filter( 'basel_header_configuration', 'basel_custom_header_configuration', 1, 1 );

function basel_custom_header_configuration() {

		return array(
			'container' => array(
				'wrapp-header' => array(
					'logo',
					'main_nav',
					'right-column' => array(
						'header_links',
						'search',
						'wishlist',
						'cart',
						'mobile_icon',
					)
				)	
			),
		);
}
