Oustanding demand paid and adjusted also

Sir
I have paid oustanding demand on 15/04/2022 for A.Y. 2014-15.
and the same demand is also adjusted from the refund of A. Y. 2021-22 on 06/05/2022.
Both the payments are showing in form 26AS of A. Y. 2014-15.
What to do sir as I have paid this two times to take refund of one transaction.
thank you sir
