[Python] AWS CDK (Python) - DLQ Queues and Retry Queues have redundant Names

I'm trying to figure out why our SQS queues have the name of the queue listed twice in the their names:

StackName-queuenamequeuenamedlq###

StackName-queuenamequeuenameretry###

Here is the relevant code:

self.dead_letter_queue = sqs.Queue(self, f"{queue_name}_dlq")
fault_queue = self.dead_letter_queue

if use_retry_queue:
retry_queue = sqs.Queue(self, f"{queue_name}_retry")
fault_queue = retry_queue

# Create main queue
self.main_queue = sqs.Queue(self, queue_name, dead_letter_queue=sqs.DeadLetterQueue(max_receive_count=retries+1, queue=fault_queue))


I would expect the names to not be redundant.
