Stereo Mp3 only Left Channel Plays

I have a stereo mp3 I created in Studio One. There is data in both channels but only the left plays a sound. I have a snapshot as an attachment. Thanks

How are you playing it / listening? (example: Listening to Audacity via Senheiser HD22 USB, plugged directly into my laptop’s USB port)
What do you hear from the right channel?
