Close Captions MXFOP1a

I've noticed that the close caption options are greyed out (disabled) in the MXFOP1a settings in Media Encoder. This is very problematic as that is one of the few file formats that allow for embedded captions and I rely on it heavily in Broadcast workflows.

This can be worked around currently by rendering directly out of Premiere. But those caption options should also be accessible in Media Encoder.

CC has been available for MXF files for years, and we've relied on them essentially as long as Premiere has been able to output Closed Captions. I think they got overlooked in the new Export implementations. If this bug can be corrected it would be very helpful.

Thanks
