Trying to export 608 captions for a .MXF broadcast delivery but the text keeps getting burned onto the video.
Upon export, if I bring the file back into Premiere it shows that the file has embedded captions but is also baked in.

Export Settings:
MXF OP1a
29.97fps
Progressive
AVC-Intra Class 100 1080

Adobe support struggled through troubleshooting before disconnecting. Any ideas of what's going on? The cache has been cleared, tried creating new projects, wiped premiere pro and reinstalled, etc.
