Hi,
Sorry for the issues. That is an overzealous warning message to help people find conflicts if they exist.
Since everything is working you do not have to change a thing.
To remove the message please add the following to your theme’s functions.php:
// remove slug conflict admin notice
if (class_exists('Tribe__Events__Admin__Notice__Archive_Slug_Conflict')) {
remove_action( 'admin_init', array( Tribe__Events__Admin__Notice__Archive_Slug_Conflict::instance(), 'maybe_add_admin_notice' ) );
}
Let me know if that helps.
Thanks
