Hello @aksdjfhlk23fkjhsa
Thank you for reaching out to the Community regarding your issue, although I am sorry to hear that you are experiencing issues with your Paypal. There is the chance that the transaction might not have cleared just yet causing the issue. It could also be that the payment might have been mistaken for the payment but that's difficult to say as well.
With this being the first time this has happened I would wait to see if it's a one-time occurrence or it's something that's consistent. You should be able to add the void into the register then if it does come in it should match if it's the same amount/payee.
Please let us know if you see a similar issue again and we can take a deeper look.
Thanks,
Quicken Francisco
