Drupal 8: Entities neeeds to be deleted before importing error

The following was seen during configuration import (drush cim)

1  The import failed due to the following reasons:                                                                                                                                
2  Entities exist of type <em class="placeholder">Shortcut link</em> and <em class="placeholder">Shortcut set</em> <em class="placeholder">Default</em>. These entities need to   
3  be deleted before importing. 

Fix by running this:

1drush ev '\Drupal::entityManager()->getStorage("shortcut_set")->load("default")->delete();'
