Automatic Ducking options disappear after adding clip to bottom audio track

Win 11
Shotcut version 26.9.6

I set my bottom most audio track to be my background music so I was excited with the auto-duck features. I can set it but when I add my audio clips to the bottom the properties with the “Automatic Ducking” options disappear. They still seem to be affecting the output though. I find if I save and close it and click on the track name area it will be back and I can change it. However, as soon as I click on the clip it will disappear again and I can’t change it. Save and close, then I can change it again. It only seems to disappear on the track that I click to select a clip. So I can reload the save, click on a clip on a different track and the BGMusic track I can still edit the ducking properties. As soon as I click on the track in the BGMusic then the Ducking properties disappear again.

Let me know if you need a screen recording or full logs:

This is at the end of the log when I reload and clicked on and off the clip:

As soon as you click on the clip, the Properties windows shows the properties for the clip. So you would need to click on the track header to change the properties panel back to the track properties.

Can you share a screenshot of what Shotcut looks like when the properties panel is blank?
