Can only export a single track

Apologies for the noob question, but I’ve been searching for an hour now and can’t seem to find the answer. Just started trying to use Ardour for the first time (v5) and trying to export a session. Although I can hear all of my tracks on the master channel, the export function only lets me export a single track. I suspect this is a routing issue, but I’m don’t know what settings to use, and the tutorials I found were for a previous version. Please help!

quick test: can you still hear something when you mute the master-bus? If so, then there’s additional routing (direct track outputs or something)

Then Menu > Session > Export . Make sure that in the “Channels” Tab the master-bus is selected (it is by default)

see also - scroll down the “Channels” are near the bottom of the page.

Thank you! I was exporting from the Region menu, not the session menu, your post pointed me in the right direction. Appreciate it!
