Hi there, CHouse1.
There is an ongoing product investigation about Unable to process employee's Super batch with SMSF due to a validation error "ABN didn't match and SMSF Details are mandatory for SMSF fund". I recommend getting in touch with our Customer Care Team and reference the investigation INV-117362 to discuss it with them and be added to the affected users. That way, you can receive email notifications or any updates.
