I am using v3.5.3 and I just realised that when I manually record a payment it sends an email to the customer without attaching the paid invoice(s). Why does this happen? Is there any way to change this behaviour? I checked the email template for "Payment Received (Manual Entry)" and yes the "Include Any Attachments" option was checked. I need to know if this is normal operation that others have experienced or is this a fault with my setup?
I have another weird issue, not sure if it will happen a second time but I recorded a payment and on the invoice it showed the amount applied as twice the value I entered along with a balance that was negative. So for example say the customer had an unpaid invoice owing $100, I record $100 payment, pdf invoice shows amount applied = $200 and balance = -$100. So I unapplied the payment and ended up with a loose credit of $100 and Due $100, 5 mins later cron ran and applied the loose credits and all of a sudden the pdf invoice is correct.
