Confusion in First Name/Last name on Dropbox application form

[virgopal]

Dear immihelp:
Sub: First name& Last name confusion in Applicaton for visa(Dropbox).

Both PASSPORT and earlier B2 Visa details:
Surname: XXXXXXX XXXXXX XXXXXX
Given Name: YYYYYY.
I have already created DS-160 with my above Passport details and got confirmation barcode code AA00ZZZZZZ
Name displayed on DS160 confirmation page:
XXXXXXX XXXXXX XXXXXX, YYYYYY
B.
Created my profile, using Passport details as below on "Application for visa" page
First Name: YYYYYY
Last Name: XXXXXXX XXXXXX XXXXXX
2. Now I have started to apply for B2 visa enewal for Drop box ,with the above profile values:
3. Now,I am on Payment page.
The name displayed on this page(before making payment)
YYYYYY, XXXXXXX XXXXXX XXXXXX
I can see two different displayed names.I believe First name and last name got interchanged(comparing the displayed name on this form with DS160 confirmation and Passport) in this form, though I have filled correct details.
I request you to clarify if there is descrepancy in final name displayed now is correct or needs correction.I request you to clear the confusion before proceeding with MRV payment . If not, does the profile created on application form needs any correction?
Thanks. Excuse me for long post
