Confuse on which visa category my H1B appointment scheduled?

Hello,

My first time H1B visa stamping has been scheduled for February 2023. It is for drop box application. But, I have notice conflict on my application type whether it is drop box or need OFC as well? is as below:

  • On my appointment confirmation letter it only shows 'VAC details’, not Consular appointment at all.
  • While on my appointment history screen shows, Visa priority: Regular.

It would be helpful if anyone can give some clear idea on this.

Thanks
