I am having a very odd problem with an exposed filter in one of my Views. The page I am talking about is here: http://epsindustry.org/eps-packaging-map2
When I select one of the last 2 options in the menu (EPS Packaging Recyclers or Loose Fill Recycling Drop-off) I get an error that says
An illegal choice has been detected. Please contact the site administrator. This is really weird to me because it only happens with these 2 options. I don't believe they are set up any differently than the other taxonomy terms. There's nothing all that special about them, its just a term that the admin selects when creating a location for the map.
Any ideas as to why this is happening or how to fix it?
