Discrepancies with NI number (Singh EEA2)

[JulietSoul]

Hello all,
I am preparing my application for the EEA2, as you may recall my husband worked in Belgium for four months and I was there with him.
While filling out the form I realised that as he was employed and paid before he started his local residence card application, his work place organised for him to have a 'fake' national registration number, which is listed on all of his payslips.
This number does not match the number on his residence certificate (the official number he got after applying for residence).
I am now unsure which number to list on the Surinder Singh page of the application and whether I should add a letter from his employer clarifying this.
Do you think the UKBA could refuse us because of this fact, even though we have all proof, including a letter from the employer, payslips, contract, rent contract etc?

Thanks!
