UM 2.0 more than one custom tab

Trying to extend the tabs on UM 2.0 I have two problems with this code:

add_filter('um_profile_tabs', 'add_custom_profile_tab', 1000 );
function add_custom_profile_tab( $tabs ) {
	$tabs['contactlinks'] = array(
		'name' => 'Contact/Links',
		'icon' => 'um-faicon-comments',
		'custom' => true,
	);
	return $tabs;
}
add_action('um_profile_content_contactlinks_default', 'um_profile_content_contactlinks_default');
function um_profile_content_contactlinks_default( $args ) {
	echo '[ultimatemember form_id=12760]';
}

add_filter('um_profile_tabs', 'add_custom_profile_tab2', 1001 );
function add_custom_profile_tab2( $tabs ) {
	$tabs['inemails'] = array(
		'name' => 'IN Emails',
		'icon' => 'um-faicon-comments',
		'custom' => true,		
	);
	return $tabs;
}
add_action('um_profile_content_inemails_default', 'um_profile_content_inemails_default');
function um_profile_content_inemails_default( $args ) {
	echo '[ultimatemember form_id=13431]';
}

The first problem is that the 2nd tab – INEMAILS does not show up at all.

The second problem is that the first tab still shows the URL argument of

…/?profiletab=mycustomtab

In other words, the URL doesn’t change.

Can you help? Thanks!
