If information is added under the Audio tab of the Location window and OK is clicked to close the Location window... If the Location window is then reopened and the Long Description edited... after hitting OK and returning again to the Location window, the Audio selection and settings have disappeared (set back to default).
This can be consistently recreated on my machine in the PC versions of 5.0.32.1 / 5.0.33.1 / 5.0.34.1 (on Windows 10). It could be an issue on my end, though I figured it might be helpful to at least pass this info along. Thank you for all of your hard work.
