Audacity adding second track after 1st

We have add to reistall audacity
When 1st track imported, if you import a second track
It wiil add it on first track same line
Instead of creating a second one
What is the problem

I just tried this on Windows 10, with Audacity 3.0.3.

In an empty project, I File > Import(ed) > Audio two .WAV files. Each one appeared in its own track.

Have you tried Tools > Reset Configuration ?
