Sorry, I wasn't too clear. The second flight is a completely different booking.
Only mentioned the first booking as it was the same TA, so I assume they booked it the same way.
Just seems odd. Initially I thought it was a timing issue, but it's been booked for around week so I'm not sure why it gives me the error message.
