"At least one piece of subtitle or closed caption content has no specified language. It is advisable to set the language for each piece of subtitle or closed caption content in the "Content→Timed text", "Content→Open subtitles" or "Content→Closed captions" tab."
I do not have "Content→Open subtitles" or "Content→Closed captions" tab and "Content→Timed text" does not have anyware to set language.
The DCP works when I load the VF and add the OV and I can see the subtitles in the Closed Caption window but the track says Unknown(). Are the two related and is this going to cause the cinema a problem?
Looking at section 6.6 of the manual the Timed Text tab has a place to specify language but this is not in the version I have

Not sure where I am going wrong.
