Hi, MelPhillps. Premiere Elements has its own forum and it's better to ask video questions there. I'll move this for you.
Welcome to the forum.
Switch to the Timeline View Mode. There, you will likely see that instead of a Clip, it IS a gap. You can Rt-click on that gap, and choose Remove Gap and Closeup (or similar syntax). Note: if you have either Video, or Audio, that is covering the gap, then it cannot be automatically closed.
Good luck, and hope that helps,
