I understand why they show this on your source, because they include also the East Germany. So you have to split the East Germany on a separate record.

My sources   - here is a bit different, because they count Win or Lose also for a penalty game.

A penalty game is considered drawn by FIFA. You should now this, I will send you a reference if you do not know. So you have to modify in this article in case of this situations. 

Other source   12 - 5 - 12.

England national football team all-time record - if you have a look here, also you will see the difference.
I did modify this articles and add colors, if you want to do it for this article also, and to split the East Germany from the main table.
You can add also ""Combined predecessor and successor Records"" a separate table for this cases. Read the England national football team all-time record article to know what I am talking about. I hope you did understand me. Thanks!  "
