Steps to reproduce

After adding external knowledge to my workflow, I received a prompt indicating that a reranker needed to be configured, so I applied the Cohere model. However, when I tried turning the reranker off, it continuously remained activated. Is the use of a reranker mandatory when utilizing external knowledge, or could this be a bug?
