Azure Cache for Redis - list firewall rules response is incorrect immediately after deleting one firewall rule and creating one firewall rule

We found when calling list firewall rules immediately after deleting one firewall rule and creating on firewall rule, the list response can be incorrect. We are calling 'Azure Cache for Redis' using code. Below is our code logs for requests and response payload.
Our process is:
1. Create two firewall rules - rule1 and rule2 (Log part 1)
2. Send a call to delete rule1 (Log part 2)
3. Send another call to create one firewall rule - rule3. (Log part 3)
4. After delete and create firewall rule finished, we send a call to list firewall rules. The response returns rule1, rule2 and rule3, but the expected response is that only rule2 and rule3 are returned. (Log part 4)
