ILR and BRP

[Chrisrice]

On 4 May 2013 my girl friends apply ILR as being 10 years as a student in this country, 25/June/2013 regarding her Biometric attend enrolment. Her details are:

04 /May/2013: Send SET(LR) application form to UKBA
09/May/2013: Received acknowledgement letter from UKBA
20/May/2013: Received first Biometric Enrolment letter request from UKBA
21/May/2013: She gave first Biometric Finger print
02/July/2013: Again received second Biometric Enrolment letter request from UKBA
03/July/2013: Again she gave second Biometric Finger print

As above detail said on 09/May, she received ack letter .At 21/May gave first BRP but on 02/July received second letter said, She have not gave she Biometric finger print on your request letter datted 20/May ,which she have already gave on 21/May/2013. Also on second letter request for Biometric finger print. On 03/July 2013 she again gave her second Biometric finger print from the same Royal Mail office. On 04/July she have attached all photocopy with as a proof and send to UKBA.

Now we want to know why UKBA keep on asking her to do my BRP twice, which she gave on first,On second time she showed to Royal mail office staff UKBA asked her to do second time which first one they said they have not received yet.Will her ILR application be problem if UKBA keep on asking her to do twice BRP.How long does it take?
