These titles will not be translated whatever I try. Look at the Video (hidden information)
Hello Jean,
Those titles are actually inherited from the app title. You can change it by editing the app from the back end. Take a look at my screen shot here, http://take.ms/IQPsJ
Perhaps it would be ideal if we could also move this to the language file to make translations a little easier. Will log this into our internal issue tracker.
I am looking at standardizing everything so that it would all be on the language files rather than some being the app title while some being in the language files
In the next release, we'll move these translations into the language file instead.
