Every time you enter the edit screen of an event, the country setting is removed. This happens even if you edit the translation of an event, so it's impossible to have the country showing on more than one translation - as soon as you enter the spanish edit screen, it disappears from english & so on.
this is quite annoying as one way people might quite likely be wanting to search the site, is for events happening in their country. but if the country keeps getting deleted, they're never going to find anything - unless the event has only one language & has not been edited since it was created.
