Hi there,
I tested locally and I see some of what is happening, but not exactly the same. On your site, when you choose “Honduras” the whole State input field is replaced with “nostates”. But what is supposed to happen instead is that the select field changes to a simple text field so that the donor can type in whatever they want there.
So because your site is acting differently than is intended, there must be something else going on. For example, those billing fields are not supposed to be output by default. The theme author must have added that line I mentioned above, or one like it.
Can you provide a link to the theme so I can take a look? If you purchased the theme, reach out over our contact form: https://givewp.com/contact-us
I would also suggest reaching out to the theme author about this.
Lastly, are you aware of any other customizations that were made to Give at all? The more info you provide the better. Thanks!
