I tried again and realised I was not paying attention to facing - I was looking at the info for one werewolf and assuming they were all the same. And some creatures only show 2 squares of threat when they actually have more. SO it does seem to be working as intended, it was just more complex than I realised.

I see now. As for some creatures showing only two squares of threat when they actually have more, all creatures that have more than one square in the info page are meant to see all along that row or column. But because the grid in the info page is only 5x5, it makes it seem like their range is limited to just two squares, which is totally on me.
I thought highlighting the attack line of sight whenever you selected a monster would've helped make it clearer, but I can see now that it still caused confusion.
Thank you for your feedback!
