Thanks

You are currently using just one taxonomy for country and regions, but actually need two (one for each).

The reason for this is that, in general, you can use a particular Taxonomy (or Category/Tags, each Taxonomy and each Custom Field) only once in the form. As suggested above, you would need to make additional custom taxonomies. This post tries to explain this a bit better (you can use a plugin to switch category terms from category to any new taxonomy that you make, so it is not so hard to do). It is a really awful preachy lecture I wrote:

Sorry about the tone, but the message is right and it links to good plugins (except taxonomy switcher I think).

IF you need to get one filter change to when another is set with an option, on the General settings tab:

Set Auto Count (both settings) to ON

And then in the Form UI:

In each field set Hide Empty to ON

In the filters in the form, you will only see options if they have already been used on existing posts. If they are just options (not yet used) they will not appear.
