Science Double Award Confusion

Hi, im applying for my ucas and i want to get it sent out asap from this post. I looked back and got confused about something....

I have a Sceince double award of a grade B and another grade B.
my problem is that i dont know how to enter it. i know where to find it on the ucas application. but im confused about one thing.

on my certificate it shows:
---------------------------------
Edexcel

name
school

achieved the following results in

THREE SUBJECTS

Science: Double Award ------- Grade B (b)
Science: Double Award ------- Grade B (b)
(another subject here)
--------------------------------

do i enter my GCSE double award twice with a BB or once with a BB in my ucas form? as in are they seperate or add into the same double award?

i just want to be 100% sure, thanks alot.
