DOC: Example of agent with redis memory is not working properly

Checklist

• I added a very descriptive title to this issue.
• I included a link to the documentation page I am referring to (if applicable).

Issue with current documentation:

https://python.langchain.com/docs/modules/memory/agent_with_memory_in_db/

As you can see here, Agent cannot extract the memory context correctly because it is not able to recognize which country's national anthem is being asked about, whereas you can clearly see in the Chat message history that Canada is the country in question. Is this a bug, and it actually works but is wrong in the docs? Or is there a new way to do this and docs haven't been updated?

Idea or request for content:

Agent with Memory in redis
