Initially everything was working well in the multi-currency environment, Am using two currencies; base is USD and secondary is UGX. Invoices in UGX valid fine but the error below occurs for USD invoices:

ValidateError
Error occurred while validating the field(s) currency_id: The selected account of your Journal Entry forces to provide a secondary currency. You should remove the secondary currency on the account or select a multi-currency view on the journal.

I dont want to remove the secondary because the invoices in UGX currency are attached to that same Account as the USD invoices but i dont seem to find the "multi-currency view" option on the journal. what can I do?
