B1/B2 VISA application

I applied for B1/B2 visa, and it was a drop box interview wavier application in China, today when I logged in to check the status, it says your option for an interview appointment, but then when I tried clicking on to make an appointment, the box of the calendar is empty, it’s now showing any date of option to choose a date to make an appointment so not sure what’s happening. I have been issued US visa twice.

Current Status showing ‘‘The current status of your passport is Origination Scan.’’ I think its on way to deliver me my passport. so I guess I don’t have to sit in an interview
