Table flag_counts already exists.

When I try to CIM to environment that already has flag installed and enabled, I get the following error:

exception 'Drupal\Core\Database\SchemaObjectExistsException' with message 'Table flag_counts already exists.' in /var/www/foo_bar/docroot/core/lib/Drupal/Core/Database/Schema.php:594 [error]

The only way I have been able to solve is to drop the table from the database and run CIM again.
