Thanks for spotting this!
The issue stems from the fact that when my original map got prettied up, one outline went missing. Here is a picture of the whiteboard I originally threw the dice on, four-ish years ago:
As you can see, there is an extra outline in between the 6 and the two 1s.
Otherwise, your assumption is true: The text is correct, the map not. I'll publish an errata on the https://moa.orkpiraten.de site as well.
