Chapter 21: UK spellings

[HaileyburyPangea]

Hi all,
I'm not sure if this is an error on my part or if I just found a mistake in the Lapwing for Beginners guide.
I'm very new and still learning, so I might just be doing something wrong, but here is what I found:
Chapter 21, under Miscellaneous briefs
The example given is organise ORG, but when I tried it I only got "org" instead of organise. I looked through the dictionary and there seems to be no ORG entry in lapwing-uk-additions.json?
