Thiele Small Parameters Tool - 2nd drop down is empty

[michimartini]

I was following the Help page, but found that I could not select anything in the "Free Air Measurement" drop down menu, as it is empty.
This was the same with the REW_linux_AMD64_5_31_3 stable release and also the latest beta release (REW_linux_AMD64_5_40_beta_56-api). If I leavet that drop down menu as it is I get an error upon hitting "Calculate Parameters".
Am I doing something wrong here, or is this a genuine bug?
OS used is Debian Bookworm, Wayland and Xorg behaved the same.

You need to have measured something to select the measurement in the dropdown. So for added mass measurement, complete both impedance measurements, one free air, one with added mass, then select them accordingly in the T/S calculator window.
