DNN5 account login module doesn't show the username and password label

Question

Hello every body,

I have a very strange issue with the account login module using dotnetnuke 5.6.8.

I have to create a new web site, every thing was ok before i added localization for three languages.

    For two languages i have no problems with the account login module, but whit the Nederlands (Belgie) the module doesn't show the username and the password label. I have added the old values in the Login.ascx.resx files but nothing change :( !

Here is the link to the issue (text label is empty !) :

Thanks for help.
