i18n-names doesnt work

[Knorkenknuff]

Hey atlassian-community
I got a realy annoying problem, 

I created a Space blueprint plugin but in the site titles there are standing the variable names from the i18n-name-key. 

In the space creation dialog all variables are correct(its the "Kundenbereich"). 

I have no idea why its not working correctly hope you can help me.

i have uploaded thie .jar to this place: dropbox

Thanks for all help and sorry for my bad english

Greetings
