so, I was watching a drama in a foreign language And it had subs around 5pm. after that there was any more dramas later on. it was my first to actually watching some on tv, dramas. then around 7:30pm another drama I've been wanting to watch that isn't able to be watched online came on,but the thing is,it had no subs. i didn't understand why it didn't have any now and it did earlier. dramas after that still didn't have any subs. does anyone know why? the specific channel 18 was 18.3.
