A single state is not showing up

Hello,

I have successfully put up about 20 states with their regions using the html5 maps shortcode. All of them work perfectly except for North Dakota:

It is also not showing up in the “Map Preview” section of the plugin settings.

I have compared all the settings against a state that is working properly and don’t see any differences in the settings.

Thanks in advance for your help.
