#Answer
PhoenixCurrencies claims Vault at a low priority, so an economy plugin you already run keeps Vault until you say otherwise. When another economy wins, the console says which one on startup.
Raise the Vault Priority above the other plugin's, and run /pcur reload, or remove that plugin. Also check that Vault is installed, the hook is enabled, and the Vault Currency names a currency that exists. The console warns when it does not.
