Search function doesn't work

When I search for a video in YouTube (outside of Watch2gether), I get the most relevant results first. In Watch2gether, the results are often random. Sometimes I get relevant results but usually it’s just a huge field of videos with maybe one of my keywords. This wasn’t happening before I installed the Chrome plugin that allows me to add videos to a Watch2gether playlist directly from YouTube, so I wonder if that’s causing a conflict. My searches are primarily for karaoke, so for example, “Shawn Mendes if i can’t have you karaoke”. Until this is fixed, I’m putting all my vids in using the plugin directly from YouTube.
