So I wrote waec in 2020 and didn't bother to get the certificate cos I thought the waec result printout would be enough.

I later realised I was wrong and requested a physical copy of the waec certificate. I paid around 6k and realised that my name as been wrongly arranged.

I have the result printout with me and the name arranged here is correct.
I know there are two standards way of writing name in Nigeria.
First name, middle name, and last name.
Or
Last name, first name, and middle name.
The name on my waec printout falls under the second category, but the name on the waec certificate invoice doesn't fall under any.

How is it even possible that the waec result printout is different from the certificate? Is it just the invoice? Would it be changed when I collect the actual certificate?
Pls, I need answers.

I included two pictures. One is the result printout, and the other is the certificate invoice, to give you an idea of what I'm talking about.
