Problem with latest Audacity version 3.1.0

Hi There ,
Just downloaded the latest version of Audacity 3.1.0. I am on Windows 10. The Import audio function works fine importing WAV and MOGG files. HOwever, the MKV files that worked fine on the previous Audacity version, now have a problem. All the channels show the same waveform. Instead of being 2 (Stereo) or 6 (5.1) separate channels, they show up to 6 copies of one channel. Has anyone had the same problem importing MKV files into Audacity since installing the latest version?

That’s a bug. I understand that it will be fixed soon in a hot-fix release “Audacity 3.1.1”.
