Can't change the preferences menu to GUI if the previously selected menu wasn't GUI
Preferences > Multiplexer > Default values
– I'm on this menu. I'm clicking Cancel. I'm opening the preferences again and I'm in the "Default values" menu (from where I left). I'm clicking on "GUI" (from the list on the left). Nothing happens, I'm still in the "Default values" menu and not in the "GUI" menu.
This anomaly is present in MKVToolNix GUI v48.0.0 and v49.0.0.
