I've got a problem translation my site title with the Configuration translation module. I set my set title to let's say XXX which is not displayed by the tamplte at all. Instead, it always attaches "| Drupal" string to the end of the node title.
When I click to add translation, translate the string to let's say YYY and save the form, everything appears to be saved correctly, the English version of my site even displays the correct title. However, the form for adding Site information translation still displays an "Add" button as if nothing had been added before and the default version of the site continues to display the "| Drupal" string even though my site name is set to XXX.
Has anybody else experienced the same behaviour?
