Extra Easy New and confused

Joined slimming world on Thursday I have been before but it was 5 years ago things have changed quite a bit what I am confused about is the extra easy days can't get my head around it. It was always red or green days . I am reading the book on the diary it says 1 choice from a 1 choice from b on your healthy extras then in the book it's says choose once or twice from a and twice from b from an extended healthy extra b. Can't get my head around it please anyone help

For Extra Easy you are allowed just 1 A and 1 B.

For Original or Green you are allowed 1 or 2 As (up to you) and 2 Bs.

You can still do green and original days, if you're more confident with that. Loads of us do

The basics of EE are....
* 1 A and 1 B.
* If it's free on Green OR free on red, it's free on EE.
* Aim to eat 1/3 Superfree foods each day. Superfree used to mean 'foods that are free on both plans', but it now relates only to the fruit/veg items listed on page 11 & 12.
