hi, I reproduce this case follow your step, and I found this case might within expectation. When use `./bin/pulsar-admin topics unload $TOPIC` command to unload the topic, the NonDurable subscription will be cleaned. So when the consumer reconnected to the broker, the broker will create a new non-durable cursor, the code detail is in `PersistentTopic#getNonDurableSubscription`. As shown in the screenshot, the entryId will be reduced by 1, which results in topic stats msgBacklog being 1 instead of 0.  -- This is an automated message from the Apache Git Service.
