Need help regarding References sequence

Something I just realised, on the Refereee's declaration form it has the following sentence:

"For all applications, the second referee must be the holder of a British citizen passport and either a professional person or over the age of 25"

My situation is that I entered the British Citizen as referee 1 and 2nd referee as the person of professional standings (non-British). If I remember, that's how it was asked on the online form. I am now very confused as the application has already been submitted. My BRP submission is in a couple of days though...

Any advice would be greatly appreciated....

Sequence does not matter.

awesome .. thanks much appreciated...
