Regions and cities should only be in one language. You can set that language by changing the language of the Maps API in the general settings.
I would point out that the template pages should be created in the main language of the site and the settings for the GD Pages should then be executed in that main language. Translations of the pages will be identified automatically and do not need to be set in other secondary languages. So, if the site is in Bulgarian, then, fill the settings at GD – Settings – Pages in Bulgarian. Other languages for that set of settings will not have an effect. All other languages will be identified as pages linked from the GD template pages as translations.
Have you already duplicated your listings into the other languages?
