Sounds like you have only a single (working) input connected, and likely on the right channel. Which is why it shows when a stereo track is recorded.
The reason it doesn't is because of the default Mono channel selection in Noel's image.

Change the default left to right and a Mono track will likley record.

Don't know what is wrong with the left side connection in your system..
