I have a 2012 LG 47lm6200 TV. I am having difficulty with subtitles when streaming from Mezzmo. My device settings are set to the LG TV 2012 profile. I have selected the appropriate subtitle file on the subtitle properties tab. The subtitle options are greyed-out on LG Menu. Please let me know what additional info I can provide to aid in troubleshooting.

Much Thanks in Advance!
