Caption not showing in exported file- Premiere 22.5.0 (build 62)

[BamBamBlock]

Captions are showing on the timeline, but when I embed them in the video export, they don't show up.  I have been successfully using this process for more than six months, with settings being defined in a custom preset.  I believe the issue started with the most recent update.
I use the internal transcription with audio on track set to "mix," caption preset to either default or CEA-708 default, CEA-708 format created on a visible channel,  and Stream Service 1.
Export is set to, MXF OP1a media format, and captions are set to embedded. 
Any suggestions would be greatly appreciated!

How are you testing to see if the captions are present?

The only direct test I did of embeds in 22.5 was both 608 and 708, and that worked okay.

I aopened files using  VLC, QuickTime and Elmedia Player.  The TV station uses their own systems.  None of them showed subtitle available.  That is how I have been checking captions for quite some time.  I encoded (embedded) using 708 and the rest of the settings described above.  I have another friend who is having the same issue, and he works at a local tv station.
