If the financial agent dies and there is a healthcare agent, what happens to the financial part?

Does the health one take over? Both are named in the same document, a durable poa, and the healthcare agent is also named to be conservator if court proceedings are started for consevatorship, But it also names the financial agent as conservator for financial, but he is deceased. There is an earlier durable poa which names the healthcare agent as the only agent. The later durable poa has language that revoked previuos poa, but the previous agent was never informed of revokation. This is in California. The later poa is not valid anymore as far as the financial cause agent is dead.
