Currency rate error message

I've just started using the software and am getting an error message when attempting to apply a payment to an invoice. The default currency rate (AUD) is showing but greyed out:
SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'currency_rate' cannot be null (SQL: insert into `eba_transactions` (`amount`, `reference`, `document_id`, `category_id`, `currency_code`, `currency_rate`, `type`, `description`, `account_id`, `payment_method`, `paid_at`, `company_id`, `contact_id`, `updated_at`, `created_at`) values (676, ?, 724024, 659046, AUD, ?, expense, ?, 133015, offline-payments.bank_transfer.2, 2021-01-18 01:49:24, 103284, 676708, 2021-01-18 01:49:24, 2021-01-18 01:49:24))

Same here, seems to be an error on the Model when using multiple currencies.
