Roku built-in Dash player is not displaying caption options correctly for the user

Roku built-in Dash player is not displaying caption options correctly for the user. Our content is provided with special accessibility audio captions for hard-of-hearing community, with 3 distinct tracks available for various scenarios in case hard-of-hearing watching, or a combination of people watching TV together (i.e. sign, voice & cues, full).

The dash manifest has distinct Labels for each subtitle track, even though all 3 have the same Language, all 3 tracks must be presented on the player With the Labels, to let users decide the best Captions for their situation.

However currently only a single track is shown, ignoring the other two.

How can I get all three options to show for all content?
