Hi redcarlsen,
We're only tracking issues with the latest beta versions in this forum. If you have problems with a non-beta version, or general usability questions, please contact our Technical Support Team:

Just a rough guess from what you are describing: you might be recording audio into the Arrangement View, but are playing back something in Session View, which would override clips in the Arrangement. You probably need to click the global "Back to Arrangement" button.
Best,
Nico
