请写一封英文学术风格的信给出版社编辑咨询文章出版费用已经通过国际汇款的方式缴纳但是在MDPI平台上仍然显示未付款并且收到了付款提醒。在文末附上有效的付款证明

Dear Editor,

I am writing to inquire about the publication fee for my article, which I have already paid via international wire transfer. However, on the MDPI platform, it still shows as unpaid, and I have received reminders to pay the fee.

I am attaching the proof of payment to this email to show that I have already made the payment. Please let me know if there is any further action required from my end to confirm the payment and ensure that my article is published.

Thank you for your attention to this matter.

Sincerely,

[Your Name
