EntityStorageExeption: block xxx already exists

Uncaught PHP Exception Drupal\Core\Entity\EntityStorageException: "'block' entity with ID 'funkymenu' already exists." at D:\inetpub\wwwroot\nhd-intra-1\core\lib\Drupal\Core\Entity\EntityStorageBase.php line 425

I get this error when trying to put the same menu in two different groups. I need to do this because the menu appears in a different region for "group 2".

I'd rather not have to make duplicate (triplicate) clones of the same menu. Is there another work-around? I tried to add th non-superfish version of the same menu in group 2, but got the same error.
