Has anyone here scheduled a cr1 appointment online on ustraveldoc.com before ??

So to make the long story short

we received packet 4 for our cr1 visa on November 1st after almost a year and a hlaf of sending our package to the USCIS. Our appointment was scheduled by the NVC at the US embassy in Cairo on December 13. I was unable to attend due to family emergency, i have emailed the embassy later and they replied that my case is ready for interview and i should schedule an appointment online at the site ustraveldoc.com and so i did and got an appointment on April 4. My real concern is they have sent a MRV code for fee payment wich i know nothing about it, we already payed all the fees required and it shows paid on CEAC and my understanding is the only fees left is the USCIS 165 $ which should be paid on the day of interview after you get approved. And they're mentioning some form DS160 which I know nothing about it! After i googled it, i found it's a form for non immigrant visas and k1 visa! However the new appointment letter shows clearly it's a cr1 visa!! How is that possible ?? I'm really confused and unable to get any help from the live support
