Response to Outstanding Demand Paid before Acceptance

I made a mistake. I had an outstanding tax demand showing for some time. The amount was small so I decided to just go ahead and pay it as my CA suggested.

I paid the tax and then I realized I haven't accepted the demand before paying it. I then accepted the demand. 

Do I have to pay the demand again? How do I make this right? It is still showing under E-File > Response to OutStanding Demand tab. I have the challan with me and bank statement too. 

Thank you.
