Can you see signal on the meters in the Mixer? If you can, take a screenshot and attach it here.
I can - on the track that's record armed, and on the original software instrument track, and on the bus that I'm feeding the software instrument track (which is set to no output).
To check I'm definitely hearing the record armed track, I changed the output to another one from my Apollo - on my main outputs I can now see that it is definitely sending to that output, ie what I'm hearing is, for definite, the record armed audio track rather than something else that's routed weirdly somewhere.
Obviously if I had software monitoring enabled I'd expect to see something like this behaviour, but I definitely wouldn't for a normal record-armed audio track when software monitoring is turned off.
(and sorry but the tracks are miles apart on the mixer and I'm not sure what you'd be able to see of any use on a screenshot...)
