We are sorry that you've got this impression, however, the theme works correctly and all our themes do get strictly tested before they even can be released.
We do believe that the theme is well documented, and we do understand that it might be confusing sometimes but you can find our themes documentation here as well as many great articles, and video tutorials that might help you on the way developing your website.
Please check if you have updated the latest version of the theme and its plugins. If you need instructions on how to update the theme and included plugins, you can refer to the following article: How To Update A WordPress Theme And Plugins.
Issues can occur if you miss updating the Core plugin, and after you finish the update procedure, make sure that you navigate to Mikado Options > General and click on Save Changes to generate a new dynamic CSS file.
The theme is working correctly on our local installation and it's compatible with WPML.
