If it’s that simple,
- set project sample rate to anything other than 44k
- record audio file
- do Tempo Detection
- move a barline using timewarp tool
There must be more to it, as it worked as expected for me.
Sorry to say, without a clear way to reproduce, there’s no way to analyze the problem. In this case, Steinberg support would have the time and resources to help someone figure out how to make the steps.
