The "forced" one, correct?

Actually in this case it was the SDH track that was displaying after playback correction/HLS conversion

Ah, okay, sorry I missed you were streaming with HLS.

Can you get us this specific item to test with?

Yes let me confirm I can still reproduce this after the latest app & server updates and I will PM it to you

I have PMed EBR with the test file. I can still recreate the wrong subtitle track being displayed when streaming via HLS.

Okay, I've confirmed with your sample that this does appear to just be the age-old problem of the Roku player simply not allowing us to select any other sub track if one is marked "forced".  If that flag is set, it doesn't matter what we tell the player, it is going to play that track.  Using MKVToolnix I removed that flag from that track and then I can freely select any of the three sub tracks and they show properly.

Is the item direct playing? When using HLS you should still be able to change the subtitle. If you use playback correction on the original file not modified by MKVToolNix and you should be able to then change subtitles. It should only be when directly playing the container that the default/forced flags matter. Once we kick it into HLS we should be able to work-around whatever the Roku is doing poorly.

Yes, he is aware of that from earlier in the thread I believe.
