member administration causes a bug

When I install Ultimate Member or another plugin with the same intent and I go to menu I get the following message:

Too few arguments to function um\admin\core\Admin_Navmenu::wp_nav_menu_item_custom_fields(), 4 passed in /home/vhosts/vocomotion.nl/httpdocs/wp-includes/class-wp-hook.php on line 287 and exactly 5 expected

I hope there is a solution for this.
