Webplayer issues: asset downloads, transcript avatars

I have some issues with the web player in combination with the publisher.

Recently, the player stopped showing contributor names and avatars in the transcript, even though voices are assigned in the publisher.

Also, the download tab only shows one asset, which happens to be the one I last added to my podcasts assets. I marked it to not be included in download interfaces, but it shows up in the web player download tab. Other assets, that should appear here (and did so before) are no longer available.

Any clues what might be going on here?

Found out that this only occurs, if the episode has a contributor that is not marked as visible. Opened an issue on GitHub.
