Typically, when we users 'Update' an addon using the Twitch client the latest version is downloaded and installed. A few addons like yours have now started including a classic version in the same project as the retail version and it's causing the classic version to be interpreted as the latest version. We have to manually revert the update to the retail version.

Please separate your projects if the code base can't support both versions. Thanks.

I just opened the Twitch app again and now it's not doing this so I'm not sure what happened.
I'm closing this issue. Thanks.
