Audacity is selecting multiple tracks. I mean, if I select track 2, even track 1 gets selected and edited at the same time!?
Drag and Drop is also NOT WORKING!
If I open the audio file, a new window of Audacity Editor opens to each number of audio files!!!
What the hell is going on I don’t understand! The same is the case with both Audacity Audio Editors, RDFE423F v2.2.0 Alpha and v2.3.1 Alpha-14fe11f.

Don’t use alpha versions of software unless you are an expert.

The current version of Audacity for Windows / macOS is Audacity 2.3.0 and is available via the Audacity website: https://www.audacityteam.org/download/
