layer slider won't update

Layerslider shows error:
Warning: call_user_func_array() expects parameter 1 to be a valid callback, function ‘hb_update_link’ not found or invalid function name in /…/wp-includes/class-wp-hook.php on line 300

Says needs to be version 6.5.8, but 6.5.7 installs when I deactivate, delete and reinstall.
