Troubleshooting Langchain Query Evaluation in Phoenix UI

hi team, i have some issue when evaluating langchain query, when i run this code (which i follow from the notebook tutorial) def evaluation(self): queries_df = get_qa_with_reference(Client()) retrieved_documents_df = get_retrieved_documents(Client()) it always evaluate all the queries in my Phoenix UI, I've tried filter using span_id but not working, any idea how can I just evaluate one query instead of all in the UI?
