Could there be a problem with saving a selected language under my langauges on the ui?

When passing through the ui using reference application 2.9 snapshot on sdk,i tried to change the languages that i got under my Languages button.Selecting a primary language could automatically select the proficient languages but not for all the available languages,on saving i did not get any action taking place.First i thought it could be the database that i was running which was maria db ,later i tried with the demo server and it was the same thing,It looks like some thing is missing on the pull requests that were merged from this ticket. Any suggetion on this?? @dkayiwa @darius

Which version of adminui module are you running?
