Delete a language in Traslation Manager

How Is it possible deselected a language in traslation manager???

Thank You

You mean prevent languages from showing up in the language selector without actually deleting them from the translation manager? ...or do you mean remove the languages entirely and permanently?

In traslation Manager are selected 4 language. I want delete one language from traslation manager

click on (Not on the select box) the wanted language (it should be then highlighted) and click on the delete icon next the language column
