I signed with a wrong signature

[leyloqaali]

HI
I have changed my name by deedpol while still having ILR so i had to update my biometric card which I did and applied NO LIMIT. When I was enrolling for the new biometric card I used my old signature rather than the new one and I did not realise until I received my biometric card with my new name and old signature. What I can do? how can i Change the signature and what process do i follow? am i require to make a fresh NO Limit application or there are other ways to do it?.
please help

thank you
