Issues with subtitle language

hi guys. I am using raspberry pi device. ı have installed osmc 2017-08-01 release disk image and adjusted kodi confluence default skin. but when ı go through settings>player>language the osmc does not allow me to go on languge section and not allow me to change default movie subtitle language from English to any other language . Language section is visible and in fact wireless mouse could not select language section. Has OSCM team forbide to use any other language except English ? How could I come over this problem ?

Thanks.

Please update to the latest version of OSMC first.
