Hard to describe unless I'm the only one to have this issue but, seems that if a stream has a spaced (with underscores) name, it only displays the first word of the name resulting is a black video or possibly a wrong channel video if one were to exist as showned in the screenshot.
This issue has been fixed a while ago. If you are still having this issue after downloading the Chrome Web Store version or installing either the dev_build or main version from my GitHub let me know.
