create a recording from separate tracks with labels

Hi,

OS: Windows 10
Audacity 2.2.1

I have created an audio recording adding a label to each section but in exporting the file, each section has been split as separate tracks.

My intention is to master a mp3/wav recording with each section labelled so that each “track” can be listened to separately as with tracks in a cd.

Grateful if you could help me in the process.

TKS
