I faced this exact issue this morning. After several minutes, I figured it out. I was trying to use a Highlight, but the system refused to give me dialog to make a trailer. We are limited to making a clip from the highlight, which is not very easy. I ended up downloading and uploading the same video to get it to accept it as a source for the trailer.
