Localized messages not showing

[scpc0609]

I am using 8.1 silverlight app. I recently added few languages and translated my main resources. However, the rate-my-app component does not recognize the current language and shows the messages in English only. I have localised for culture neutral languages (eg. fr instead of fr-FR). Please help if I am missing something. The component was installed via NuGet and I did not do anything apart from adding the below tag to my main page:

<rma:FeedbackOverlay x:Name="FeedbackOverlay" CountDays="True" FirstCount="5" SecondCount="10" FeedbackTo="myemail@xyz.com" ApplicationName="{Binding Path=LocalizedResources.ApplicationTitle, Source={StaticResource LocalizedStrings}}" CompanyName="{Binding Path=LocalizedResources.ApplicationPublisher, Source={StaticResource LocalizedStrings}}" />

there is a RateMyAppGuide.pdf in the doc directory, it may help.
