Hi, I’m mixing sound on sequencer but every time I try to move an audio item, it goes down under all the existing tracks to a new one.

Then, when I try to move it again it goes on another new track under the last one and disappear…

Can someone help me to fix it ?

Okay I found something. The Audio tracks was pinned. When I uncheck “Pinned” Tracks go down and no longer have problems.
