I'm tracking down an issue where captions in 608 and 708 tracks and set to Roll-Up 2 (whether each or selecting all and making the change) continue to default to the first item in the list: Pop-On. Captions made within Premiere won't stay as Roll-Up 2, but captions brought in from MacCaption via MCC file maintain Roll-Up 2... which means the part of the show with those captions have Roll-Up 2 but the rest are defaulting to Pop-On, even on output.
