I need to add new languages in Sitecore 8.2 (rev. 170407) To do this, I am adding a new language by right clicking on System/Languages -> Insert -> Language.
While I am able to do this for some languages, it does not add languages for some.
For e.g: en-BE, en-CH, en-DE are created successfully
But en-IT, en-NO, en-LU are not created
What am I missing here? Is there a config entry or setting I need to modify?
Thanks in advance
