Steps to Reproduce

Run an Agent in a playground with a KnowledgeBase.

knowledge_base = CSVKnowledgeBase(
    path="data/lob_matrix.csv",
    vector_db=PgVector(
        table_name="insurance_lob_matrix",
        db_url=db_url
    ),
)

knowledge_base.load(upsert=True)
storage = PostgresAgentStorage(table_name="insurance_classifier_agent", db_url=db_url)

insurance_classifier_agent = Agent(
    model=Gemini(id="gemini-2.0-pro-exp-02-05"),
    knowledge=knowledge_base,
    storage=storage,
    read_chat_history=True,
    show_tool_calls=True,
    description="""You are a helpful classifier in the insurance business.
      You use your knowledge base to classify from a company description what
      lines of business an insurance company features.
    """
)

Agent Configuration (if applicable)

Provide relevant agent configuration.

Expected Behavior

The KnowledgeBase to be loaded once.

Actual Behavior

It appears to be loaded three times.
