Hello hotcity,
Thanks for reaching out to us!
I apologize for the issues you are facing using our plugin. It looks like your WordPress install is an English install and the translations are being managed by a third-party plugin such as WPML?
Unfortunately there are some compatibility issues between our plugin and translation plugins such as WPML. This is something that is on our radar and is very important for us to work on addressing in 2015. However, due to the nature of the plugins, the solution will most likely be a significant rewrite of large portions of our plugin which means there isn’t much of solution we can provide in the meantime to patch the issues.
I apologize for any inconveniences this issue has caused. If you would like, you can vote for the feature on our UserVoice page and get updated on progress when the issues are able to be addressed.
Thanks!
– Josh
