Filter out forced subtitle tracks from StyledPlayerControlView text track selector

I have DASH video files containing closed captions links within the mpd file, so I’m not manually adding subtitles. Some video assets have Forced language captions that I don’t want to show in the player (which is showing up twice). For example, French, German, and Spanish forced should be excluded in options user can select:

French (Parisian) (Forced) German (Germany) (Forced) Spanish (Castilian) (Forced)

French (Parisian) (Full) German (Germany) (Full) Spanish (Castilian) (Full) Marathi (Full) Norwegian (Full) Danish (Full) Turkish (Full)

I’m using the default StyledPlayerView, and have tried something along the lines of

DefaultTrackSelector.Parameters parameters = trackSelector
.buildUponParameters()
.setDisabledTextTrackSelectionFlags(C.SELECTION_FLAG_FORCED)
.build();

trackSelector.setParameters(parameters);

but with no success. I’m able to see the list of subtitles available with this:

int trackLength = trackSelector.getCurrentMappedTrackInfo().getTrackGroups(2).length;
for (int i = 0; i < trackLength; i++) {
    Utils.log(trackSelector.getCurrentMappedTrackInfo().getTrackGroups(2).get(i).getFormat(0).label);
}

Not sure if changes should or can be made here to remove the unwanted captions. Any help is appreciated, thank you.

Do we want to show the name even if it’s a ‘forced’ track? It seems perhaps a user shouldn’t even ‘know’ that a forced track is selected, since it’s assumed to be required to understand the content of a given audio track.

That sounds right. I think the UI should show CC as “off” or “none”, but the forced track should still be selected.
