IRS removed my payment.

So I owe IRS money this year, and I paid via IRS direct pay through the official website. The payment was listed on Apr 6th, and the amount was deducted from the bank account on Apr 7. However, I got another notice on Apr 26, telling me that “we removed a payment applied to your account in error.” I feel very confused about it. I will call IRS again to figure out why but I would like to know if anyone has been through similar cases?
