Cannot find Music/Soundtrack track for Remix in Premiere Elements 2026

I'm using Premiere Elements 2026 on Windows 11 in Advanced mode. I want to use the Music Remix feature to extend and auto mix a music clip to match my video length.

The problem: I cannot find the Music or Soundtrack track anywhere in my timeline. I only see Video 1-3 and Audio 1-4. I've scrolled down — no Soundtrack track exists below the audio tracks.

When I drag a music file to the timeline it only goes to regular Audio tracks (Audio 3, 4, 5, etc.) and does not show remix handles — only regular trim handles.

How do I get the Music/Soundtrack track to appear in Premiere Elements 2026 so I can use auto Remix?  I have tried my bot and no help there either
