Strange Language update warning

Hello,

looking at the Administrative panel I've seen a strange fact, there is a message telling me that is available the russian Language update (see attached images)

... how this is possible while I'm only managing english and italian languages?

and: how can I remove this warning while I'm not managing russian Language at the moment?
(I've got a look in alla the administration Joomla panel and I've not found any russian Language inside)

Thanks in advance

Roberto

Just ignore that

Ok, but is there a way to eliminate the warning?

Thanks again

Roberto

Check this, go to extension manager, then manage tab and filter selection in -select type- by language if you see russian uninstall it

Thanks Ivan, worked

Roberto
