 * Hi [@leverate](https://wordpress.org/support/users/leverate/) ,
    Thank you for
   using my plugin. It’s a very unique glitch. I will try to find a solution and
   will get back to you. If you found anything related to this issue. In short. 
   I think it’s due to the page was not loaded properly when you click the back 
   button. As you know, the browser tries to restore the form/page data on back 
   button click. So It might be something related to browser function.
 * Regards
    Narinder.

 * After updating the plugin, the pages are loaded, but the error appears and the
   drop-down list of phones is not displayed, and everything is normal with the 
   countries
