This occurs when the top-up operation fails due to device issues or communication issues. Records of the attempted top-up may temporarily appear in statements but will not be billed unless reflected in your Suica's balance. They will be deleted after a set period (varies by card issuer). 

If you have questions or concerns about credit card statements or what shows up in your Wallet app, contact your credit card issuer. For debit or prepaid cards, please refer to this link. (https://apfaq.mobilesuica.com/faq/show/6898?site_domain=wsm)
