MIDI type 1 file not importing onto separate tracks

Windows 10 Audacity 3.1.2 Should import type 1 MIDI files into separate tracks but all import into a single track of 16 channels. And I can’t seem to separate them after the fact. Is there a step I’m missing? The file comes from an export from Steinberg Nuendo (latest version) exported specifically as type 1 MIDI.

Audacity’s MIDI capabilities are extremely limited.
As far as I’m aware, importing a MIDI file always imports as a single track.

Thank you, Steve. Much appreciated.
