Don't seem to be able to have multiple allowed areas?

I don't seem to be able to select more than four areas for setting restrictions for animals. I have made a couple of extra ones on the area management panel, but I just can't choose them for some reason. They won't appear on my list when trying to assign them. I have Unrestricted, Home, Livestock and Dog Area, and then Manage Areas. I needed more because a fallout event just occurred and I wanted to put my animals into safe-zones. I have all of them available for my colonists. Is this a bug or are animals for some reason limited to locations?

Read about how many times it has felt like that was the first time I read it.

I'm sorry, what?
