@patrickt333 In the past, I have posted about this issue as well as have seen posts from other users. For whatever reason, I have never had DVDFab detect and turn on as default a forced 'translation' subtitle, at least for movies that I have backed up that do have forced subtitles. The way I have worked around this, at least in Blu-ray copy mode, is to first load the original in a software player such as PowerDVD (which does detect and turn on forced subtitles) and just check which subtitle track is turned on automatically by the player, if any, when the main movie starts playing. You could of course do the same thing using a standalone player too. Then when I go to make the backup, I make sure that subtitle track is checked in the subtitle drop-down list on the main page of DVDFab. I then tag it as a default track by clicking just to the left of the appropriate subtitle track, and a small white right-pointing triangle, or arrow, will appear next to the track, indicating this track will be turned on automatically by the player. So far this method has worked for me flawlessly and I don't believe I have missed any this way. Yes, it is an extra step and sometimes a pain because in some movies you cannot chapter through the various previews (in other words the distributor forces you to watch them, though you may be able to fast forward through them ) so it may take a while to get to the main movie.
