autoeq.app does not download a stereo impulse file despite enabling the option

[MechanoPixel]

Describe the bug Despite toggling Stereo to generate a stereo impulse file, a mono file is downloaded instead. This is an issue because EasyEffects on Linux requires a stereo impulse file. Attempting to import the generated "stereo" impulse file fails with the error message "Impulse File Not Imported: Only Stereo Impulse Files Are Supported".

This is confirmed by using mediainfo to check that both the mono and "stereo" files only have one channel. Additionally, using md5sum reveals that regardless of toggling the Stereo switch, downloaded files are always identical.

To Reproduce

1. Go to autoeq.app
2. Select headphones (In my case, Logitech G435 LIGHTSPEED)
3. Select EasyEffects / PulseEffects as equalizer app
4. Turn on Stereo
5. Click on download icon

Expected behavior A stereo impulse file is downloaded and is able to be imported into EasyEffects.

Files samples.zip Both Edge and Chromium produced files with the same md5sum: e266c0e4fd64d9432679218f2ca1d010

Firefox produced a file with a different md5sum: 8727c9aeac285212034d1d537a936baf

However, both browsers' respective mono and "stereo" generated files are the same:
